Leyla Mathis · Answer 1

If the side length of a cube is multiplied by a ratio k, the volume is multiplied by the ratio k³.

Here the side length is multiplied by 2, therefore the new volume

= old volume * 2³

= 2x^5 * 8

= 16x^5.

Greene · Answer 2

New edge of cube=4x^5

hence, new volume = (4x^5) ^3=64x^15
