If a cube is sliced into equal sized smaller cubes, which quantity of smaller cubes could be attained?
a)4 b)16 c)1/4 d)-1/5 e)1

• math -

What are the dimensions of the larger cube?

• math -

e)1 only with whole cube root

• math -

could you explain to me how to solve it please?

KokkoDeRas is right.

You need to find a perfect cube.

The only choice that is a perfect cube is 1.

• math -

Volume = length * width * height

• math -

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

what if the options are 4, 16, 25, 36, 64. How would the answer is going to change? I think the answer is 64. could you tell me if the 64 is the right answer?

for Ms.Sue I understand but you have to choose an answer ... but maybe I'm wrong

For jhonn YES

• math -

Yes. The cube root of 64 is 4.
