Answer 1

Answer:

The answer would be option A

Explanation:

Answer 2

The height of the cube is 9 cm, Which is mentioned in option D, if the volume of cube is 729 cubic centimeters.

Explanation:

The given is,

                 Volume, V = 729 Cubic centimeters

Step:1

         Formula for volume of cube,

                                     $Volume, V = a^{3}$...............................(1)

        Where, a - Side of cube

        From the given value, Volume, V = 729 Cubic centimeters

        Equation (1) becomes,

                                                $729=a^{3}$

       Take cube root on both sides, the above equation becomes

                                                   $a=\sqrt[3]{729}$

                                                      $= 9$

                                                    a = 9 cm

                          Height of cube, a = 9 centimeters

Result:

        The height of the cube is 9 cm, Which is mentioned in option D, if the volume of cube is 729 cubic centimeters.
