Question

Best gets brainly.........

Answer 1

Answer:

4

Step-by-step explanation:

V = $a^{3}$

To get a side length, you have to do the cube root of 64.

4 is the cube root of 64.

To find the cube root of a number, you want to find some number that when multiplied by itself twice gives you the original number. In other words, to find the cube root of 64, you want to find the number that when multiplied by itself twice gives you 64. The cube root of 64, then, is 4, because 4 × 4 × 4 = 64.

Answer 2

Answer:

4

Step-by-step explanation:

To find the cube root of something, the easiest thing to do is look and see what the smallest factors of that number is.

64 = 2*2*2*2*2*2

Now how can that be separated into three of the same number?

64 = 4*4*4

So we can now write:

$\sqrt[3]{4*4*4} \\\sqrt[3]{4^3}\\4$

So the length of each edge is 4 feet.
