How to Get the Maximum Volume From a Cuboid Introduction I am doing an investigation into how get the maximum volume from a cuboid using a square with smaller squares cut out from each corner to then fold it up into a cuboid. Cut out the red squares and fold inwards on the blue lines to get a cuboid. To get the maximum volume from the cuboid you need to work out the sizes of the squares you want to cut out from each corner. The formula I used to work out the volume for each cuboid
Swiss Alps about 3,353 metres above sea level and flows north, passing through or bordering Switzerland, Liechtenstein, Austria, Germany, France, and the Netherlands and then its mouth is located at the North Sea. The Rhine is usually at its maximum volume during the seasons of spring and summer; this is due to the fact that there is the melted water of snow and glaciers. In this enquiry I am looking at the aspect of river flooding in the Rhine, particularly in 1995. A river flood is when a river
The Open Box Investigation The aim of this investigation is to find the largest volume within for an open box with any size square cut out I will be increasing the square cut out by 1cm until I reach a point where the volume decreases. At this point I will decrease the square cut out by 0.1cm until I reach the maximum volume. This will be done on several different grids until I see a pattern which I will then use to create a formula. I will record my results in a table for the different
this activity is to determine the size of the square cut out which makes the volume of the box as large as possible for any given rectangular sheet of card. 1. For any sized square sheet of card, investigate the size of the cut out square which makes an open box of the largest volume. 2. For any sized rectangular sheet of card, investigate the size of the cut out square which makes an open box of the largest volume. Question 1 ---------- I began work on question 1, which was to investigate
50cm, which he uses to make drains. The semi-circle is the best shape for a drain. Prove this. I will prove this by comparing its volume to that of other shapes. On older houses there are semi-circular drains but on newer houses there is fancier ones like pentagon shapes. Is this because they are better or is it simply for design? To find the volume of a 3D object I have to find the area of a cross section and then multiply that by the length of the object. To make it easier IÂ’m going
Pressure The three scientists Boyle, Amontons and Charles investigated the relationship between gas, volume and temperature. Boyle discovered that for a fixed mass of gas at constant temperature, the pressure is inversely proportional to its volume. So in equation form this is: pV = constant if T is constant Amontons discovered that for a fixed mass of gas at constant volume, the pressure is proportional to the Kelvin temperature. So in equation form this is: p µ T if V is constant
dotted lines to make the box. The main aim is to determine the size of the square cut which makes the volume of the box as large as possible for any given rectangular sheet of card, but first I am going to experiment with a square to make it easier for me to investigate rectangles. I am going to begin by investigating a square with a side length of 10 cm. Using this side length, the maximum whole number I can cut off each corner is 4.9cm, as otherwise I would not have any box left. I am
Investigating the Volume of an Open Box The aim of this coursework is to investigate the volume of an open box constructed by one piece of rectangular card that has all four corners having had squares cut out of them. Firstly I will be studying the volume whilst changing the side of one length of the cut out square and the size of the original rectangle card. After I have investigated this relationship I will try to find out the formula for finding the cut size to get the largest volume for any specified
The Factors Affecting the Rate of Reaction of Indigestions Tablets With Acid Planning, To start the investigation I thought about what affected rates of reaction. I managed to come up with 4 ideas: 1 Surface area 2 Temperature 3 Concentration 4 Mixing of the substances (stirring) I decided to do 2 different preliminary experiment so I could chose the best variable to investigate and see what equipment was necessary to provide us with an accurate set of data. Our first Preliminary
two different sized cylinders. Accuracy is a measure of how close something is to its true value. To determine the accuracy we had to measure the volume and compare it to the theoretical volume, finding the relative error. Following this we used the density of water, 0.99720 g/mL, along with the mass we determined with a scale, to determine the volume of water in a 10 mL pipet using the formula D=mv. Objective: The purpose of this lab is to determine which cylinder, the 10mL or 100mL is will produce
Expansion and Contraction of Materials When most materials are heated they expand and this increase their volume. One example of expansion is the fitting of the starter ring gear to the flywheel. The gear is heated until it expands sufficiently to pass over the rim of the flywheel, and when it is cool the gear tries to return to its original size, this gripping the flywheel with considerable force. All metals do not expand equally when heated through the same range of temperature, e.g. aluminium
below this it shouldn't be a problem. Method: To perform the titration the first thing that needs to be done is to dilute the HCl to a suitable concentration, to increase the accuracy of the results it would be helpful if the volume of the alkali equalled the volume of the acid used. We know that the concentration of the alkali is close to 1g/dm‾, which is roughly equal to 0.013mol by using the equation Mass = Mole * RAM.
determined that the best way to conduct this experiment is to do a titration. This will allow me to determine the amount of impure citric acid required to neutralise a known volume of 1.0 M sodium hydroxide. Consequently, by calculating the correct volume of pure citric acid that would be required to neutralise this volume of sodium hydroxide, I can calculate the percentage purity of the citric acid. Calculating the Amount of Citric Acid ------------------------------------- In order
Measuring the Viscosity of a Liquid Aim The aim of this experiment is to find out how fluid Bath Oils really are by measuring its viscosity. Plan The first thing that I'll do is to measure the spheres volume by first measuring its radius. I will then, by calculating the spheres mass, be able to calculate the density of the sphere. This will be used later when calculating the viscosity of the bath oil. I will then find the density of the bath oil, also used during calculations later
50ºC, 60ºC, 70ºC Distilled Water Paper towels Independent Variables In this experiment there are several possible independent variables that could be changed, these consist of: * The surface area of the beetroot cylinder * The volume of the beetroot cylinder * The temperate the experiment is done at * The time the beetroot cylinders are left in the water * Amount of water used * Age and condition of beetroot used The independent variable that I will be changing

Students can get the formulas and example problems in online. In this article we shall see how to calculate the volume and surface area of three dimensional shapes. Online 3 dimensional shapes lesson help – Formulas: Cube: cube Volume of the cube (v) = a3 cubic units a – side length Surface area of cube (SA) = 6a2 square units a – side length Cylinder: cylinder The volume of the cylinder (v) = π x r2 x h cubic unit r – Radius of cylinder h – Height Surface area of right
the volume of amylase affects the rate of reaction between amylase and starch. Prediction: I predict that the greater the volume of amylase then the faster the rate of reaction between the starch and amylase will be. I predict this because of the lock and key hypothesis. The lock and key hypothesis explains how the substrate molecule (the starch) fits inside the enzyme. The substrate molecule is then broken up into many smaller pieces. In this experiment the larger the volume of amylase
Finding the Hidden Faces of a Cube In order to find the number of hidden faces when eight cubes are placed on a table, in a row, I counted the total amount of faces (6%8), which added up to 48. I then counted the amount of visible faces (26) and subtracted it off the total amount of faces (48-26). This added up to 22 hidden sides. I then had to investigate the number of hidden faces for other rows of cubes. I started by drawing out the outcomes for the first nine rows of cubes (below):
