A rectangular solid is dilated by a factor of 0.5.

How many times larger is the volume of the resulting solid than the volume of the original solid?

Volume of a rectangular solid is #V=abc# where, #a,b,c# are length,breadth and height respectively.

So,#(delta V)/V = (delta a)/a + (delta b)/b +(delta c)/c#

Given, #(delta a)/a = (delta b)/b =(delta c)/c=0.5#

So,#(deltaV)/V =0.5+0.5+0.5=0.15#
