KokkoDeRas is right.

You need to find a perfect cube.

The only choice that is a perfect cube is 1.

Volume = length * width * height

the test gives you the possible number of smaller cubes [a)4 b)16 c)1/4 d)-1/5 e)1]

they must be the solutions the cube root of an integer, example [a)4 b)16 c)1/4 d)-1/5 e)8] smaller cubes (e)8 cube 2

2*2*2=8

1*1*1=1
