Choices
Choose the correct option.
A) 24
B) 48
C) 64
D) 80
E) 100
Lets say the sides of the rectangular cube are x, y and z. Problem states volume is 6.   i.e,   x*y*z = 6 .   If every side is increased twice as before. then new volume is   2x*2y*2z = 8*(x*y*z)  2 *2 *2=

<output>8</output>
8*(x*y*z)= 8*6=
