Question

IMPORTANT PLEASE I NEED NOW:Find the area of each face of the cube whose volume is 729 cm

Answer 1

Explanation:

Formula of Volume=
`a^(3)` - a = side

Therefore since the volume is given you just need to find the side.

729=
`a^(3)` =
`\sqrt[3]{729}` = a

= 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Area of a square= 9 x 9 = 81
`cm^(2)`

Answer 2

81

Explanation:

square root of 729= 9

9×9=81
