the volume of a rectangular prism is 256 cubic centimeters. What is the volume of a similar rectangular prism that has edge lengths one fourth as long as the edge lengths of the original prism?
dimensions were a,b,c, volume was v = a*b*c
new volume is (a/4)(b/4)(c/4) = abc/64 = v/64
if edges are scaled by f,
area is scaled by f^2
volume is scaled by f^3
