The volume of a cube is calculated by cubing the length of one of its sides. In this case, the length of one side is 2 units. Therefore, the volume of a cube with sides of 2 units each is 2^3, which equals 8 cubic units.

Multiply the length of any edge by itself three times. This is the cubic volume in the units you used to meadure the edge. That is LxLxL = VExample:A cube 2 ft on a side is 2x2x2 = 8 ft3A cube 2 meters on a side is 2x2x2 = 8 m3
The volume of a rectangular prism is found by multiplying the length, width and height. In the case of a cube they are all the same. So you multiply 2x2x2. Which is 8. So the volume is 8cm^3.
It is written as 23 which means 2x2x2 which is the volume of a cube of edges 2, 2 and 2 and it equals 8
Each side has 2 cm of length = 2x2x2= 8cm3
Cube of 2 is 2 3 = 2X2X2 = 8
