100(.85)=x(.9)+(100-x)(.4)
85=.9x+40-.4x 
45=.5x 
x=90

Thus 90lbs of the 90 cent and 10lbs of the 40 cent.

Since the base of the prism is a right triangle, we can use the pythagorean theorem to solve for x.

a²+b²=c²
plug in the data
a²+24²=30²
a²+576=900
subtract 576 from both sides
a²=324
sq root
a=18
So x=18


The formula for the volume of a triangular prism is...

V=(area of the base)*(height)
V=1/2bh*H      where b=base of triangle h=height of triangle, H=height of prism
plug in the data that we know
720=1/2*18*24*H
720=216*H
divide both sides by 216
3 1/3=H

So x=18 and y=3 1/3 or 3.33 repeating

The product of the two

18*3 1/3=60

Answer=60
