The formula for the volume of a sphere is shown below. Example of Calculating the Volume of a Cone Volume of a Sphere This gives the formula for the volume of a cone as shown below. The volume of a cone is equal to one-third the volume of a cylinder with matching height and area of base. Example of Calculating the Volume of a Cylinder Volume of a Cone Note: in the examples below we will use 3.14 as an approximate value for π (Pi). There is more here on the area of a circle. The base of a cylinder is circular and the formula for the area of a circle is: area of a circle = πr 2 . We can say “85 centimeters cubed” or “85 cubic centimeters”Įxamples of Calculating Volume of Rectangular Prisms Volume of a CylinderĬalculating the volume of a cylinder involves multiplying the area of the base by the height of the cylinder. We write cubic sizes using a small 3 next to the unit. Milliliters, liters, gallons are also used especially when measuring liquids. There are other units for measuring volume cubic inches, cubic feet, cubic yards are all units used for measuring volume. There are 1,000,000 cm 3 in 1 m 3 – be careful not to have too much sugar! Think of filling a very big box (it would be 1 meter wide, 1 meter, long, and one meter high) with sugar cubes (with each side 1 centimeter). Why the big difference? Because in volume we have not just length we have length, width, and height. For example, there are 100 centimeters in 1 meter but there are 1,000,000 (yes, 1 million) cubic centimeters in a cubic meter. There are very big differences between units of measurement for volume. In other words, make sure the connection between what’s on paper and what it represents in the real world is made.īe sure your child is not confused by the use of volume as used when talking about loudness. Ensure your child is aware of this and does not think of the cubes, and other 3D shapes shown on paper as just being another “shape on the page.” Show them real boxes, and show how these can be drawn (or represented) on a two dimensional piece of paper. Working with volume does involve 3 dimensions. that are shown on paper as flat – there is no depth, or 3rd dimension. When your child starts working with area and perimeter he or she will usually work with 2 dimensions – squares, rectangles, triangles, etc. Notice how we get the same answer no matter what side we use to find an area. The examples below show how there are three ways of doing this. We calculate the area of one face (or side) and multiply that by its height. We need to do two multiplications to work out the volume. The volume of a rectangular prism is = length x width x height Examples of calculating the area of a rectangle The rectangular prism above has an volume of 48 cubic units. We can count the cubes although it is quicker to take the length, width, and height and use multiplication. How many cubes are in this rectangular prism (cuboid)? Volume is measured in cubes (or cubic units).
Note: To be totally smart, volume and capacity aren’t always the same – think of a box with really thick sides! Calculating Volume Sometimes you might hear questions like “what is the capacity of a box?” or “how much can the box hold?” You can assume that these questions will need a volume to be calculated. Volume measures how much space an object occupies.
This Rectangular Cuboid Calculator uses different converter function in order to generate the Output in different units such as Inches, Feet, Meters, Centimeters and Millimeters. Rectangular Cuboid is an online tool for geometric calculation programmed to find out the Volume and Total Surface Area for the given input values of Length, Width and Height.
