Question

If a cube has a perimeter of 28 cm, then the volume of the cube is

Answer 1

Answer:

Since the perimeter of cube is 28 cm, that implies that the sum of the edges of a cube is 28 cm.

Since a cube has 12 edges, we get the side of cube as 28 divided by twelve, which is approximately 2 cm. (exactly 2.33333 cm)

Now the volume is the cube of the side, i.e. 2 X 2 X 2 which is 8 cubic centimeters.( (2.3) cube =12.64)
