Answer 2

the cube root of the volume of a cube is equal to the length of the sides

Answer 3

will it be 27?

Answer 4

\[V=s^3\\
\sqrt[3]V=s\]

Answer 5

No..

27 * 27 * 27 = 19683

Answer 8

Google will give you the answer if you put 'cube root of 729' in google..lol.

Answer 9

i think its C

Answer 10

I already told you 27 is wrong because:

27 * 27 * 27 = 19683 NOT 729. 27 is too big a number.

Answer 11

27 is the SQUARE ROOT of 729, not the CUBE ROOT.

Answer 12

The square root of the 729 is\[\sqrt{729}=27\]

but we are looking for the cube root
\[\sqrt[3]{729}=?\]

Answer 23

We say that '9 cubed' i.e. 9x9x9 i.e. 9^3 is 729

We say that the 'cube root of 729' is 9
