Meters squared and meters cubed refer to different methods of measuring space. One describes the area of a flat plane, while the other describes the area of a three-dimensional area. However, it is sometimes necessary to convert between one and the other. For example, if you know the square area of one side of a cube and the cube's height, you can find the cubic area by converting from meters squared to meters cubed.
Multiply the length of the area by its width. This will give you the square meters.
Determine the height of the area.
Multiply the meters squared by the height. This will give you the area's cubic three-dimensional area.
