How to calculate the volume of a cube or rectangle: Multiply the height x width x depth, for example if the cube is 5cm x 5cm x 5cm the volume is 125. Exactly the same principal can be applied to a rectangle only of course the height, width and depth unlike a cube may all be different. How to calculate the volume of a sphere: Multiply the cube of the radius by pi, then multiply this by 4/3 so if the radius is 3, then it would be pi x 3 x 3 x 3 x 4/3 = 113 How to calculate the volume of a cylinder: First you will need to multiply the square of the radius of the cone by pi, then you need to multiple this by the height of the cone, like so - radius = 5, height = 10, so pi x 5 x 5 x 10 = 785.5 How to calculate the volume of a cone: This requires a couple of steps, firstly multiple the radius by pi, then multiply the product by the height of the cone. Finally, you will need to divide the product by 3 to allow for the shape of the cone. So it should work like this - radius = 5, height = 10, so pi x 5 x 5 x 10 x 1/3
