Volume

To work out the volume of a prism.... remember-

A prism is a shape which has a uniform cross-section. The volume of a prism is the area of the cross-section x the length.

The formula to remember is:

Area of cross section × Length = Volume

Volume

To work out the volume of a cone-

1. work out the area of the base of the cone. to do this the formula is- 1/3 3.14xH

2. then x the area by the height of the cone(make sure it is the height in the middle of the cone, not the slanted angle on one of the side)

3. finally divide your total by 3 to find your final answer.

Surface Area

To work out the surface area of a 3D shape, e.g. a prism- you need the area of both ends, plus the sum of the areas of the sides.

To work out the surface area of a pyramid you need the area of the base + the area of all the other sides.
