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
What are the dimensions of the larger cube?
e)1 only with whole cube root
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.
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
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
Yes. The cube root of 64 is 4.
