Are the ratios of the side lengths similar?
16-----> 40 is a scale factor of 40/16 = 2.5
is the other side scaled by the SAME factor?
12------>30 scale factor is 30/12 = 2.5
Yes , they are similar.
Area x height = volume
area of right triangle = 1/2 leg1 x leg2
R one volume = 1/2 x 30 x 40 x height = 600h
L one volume = 1/2 x 12 x 16 x height = 96h
the one on the R will have greater volume 600h/96h = 6.25 times greater volume
