V of original cube={4}^{3}
=64
Side of new cube=2×4=8
So V of new cube={8}^{3}
=512
Ratio of V of new cube to the original cube=512/64
=8 times
thus,answer is(D)Eight times.

Answer:
8 times
Step-by-step explanation:
Volume of a cube = Side³
Side of cube = 4 m
Volume of original Cube = 4³ = 64 m³
Side is doubled
Side of New cube = 4 * 2 = 8 m
Volume of new cube = 8³ = 512 m³
Volume of New cube / Volume of original cube = 512/64 = 8
Volume of new cube is 8 times in comparison to original cube
