What happens to the surface area of a rectangular prisim when each of the dimensions is doubled?

a) it doubles
b) it quadruples
c) it is six times greater
d) it is halfed

Answer=C

The formula for the volume of a rectangular prism is

V=l*w*h    where l=length w=width and h=height

So lets double each of the dimensions and see what it does to the volume

V=2l*2w*2h
V=8*l*w*h

So when you double each of the dimensions, the volume becomes 8 times greater, which isn't an option. Did you correctly write the question?

For example if the dimensions for l,w & h are 2

V=2*2*2=8

but if they are doubled

V=4*4*4=64

64/8=8

So it's 8 times greater...
