convert english measurements to metrics L 134 in
W 124 in
H 92 in
I took these three and multiplied them by 2.54cm I got 889cm.
I need to find the volume in cubic centimeters.
If each dimension (L,W,H) is doubled, what happens to the volume of the room?

gotta multiply by 2.54^3m since you have to convert each dimension:
(134 in*2.54 cm/in)*(124 in*2.54 cm/in)*(92 in*2.54cm/in) = 2.5*10^7 cm^3
or,
134in*124in*92in = 1528672 in^3 * (2.54cm/in)^3 = 2.5*10^7 cm^3
if dimensions double, volume goes up by 2^3 = 8 times
