Question

If each edge of a cube, of volume V, is doubled, then the volume of the new cube is
A. 2 V
B. 4 V
C. 6 V
D. 8 V

Answer 1

Answer:

When the side of a cube is doubled , the volume of the cube becomes 8v .

We know volume V is

V=s*s*s

Now s =2s

Therefore new volume v is

v =2s*2s*2s.

v = 8V

Therefore volume becomes (n^3 )*V where

n is the factor by which the side is increased or decreased.
