Answer:
4cm
Explanation:
To find the answer, if its a cube, that means all of is sides are equal.
Since to find volume, we use the equation width*height*length, then we need to find the cube root of 64.
Since 8*8 is the square root of 64, lets divide it in half.
8/2=4
4*4=16*4=64.
The cube root of 64 is 4 so the length of the sides is 4.
Hope this helps!
