How do you calculate cube root 64?

Answer 1

Either you use a scientific calculator, or you try which number, when cubed, gives 64. This one is easy, since it is a perfect cube. Try, for example, 2 cubed (2 x 2 x 2); this is 8, which is too little, so you try a larger number.

Answer 2

4 x 4 x 4 = 64, so the cube root of 64 is 4.
