Question 233495
"The area of the top of a rectangular box is 324 in.^2, the area of the front of the box is is 135 in.^2, and the area of the end is 60 in.^2. What is the volume of the box?" 
--------------------
Volume = x*y*z
xy = 324
xz = 135
yz = 60
--------
x = 324/y
x = 135/z
---------
yz = 60
324/y = 135/z
z = 60/y
324/y = 135y/60
135y^2 = 19440
y^2 = 144
y = 12
-------
z = 5
------
x = 27
------
Vol = 12*5*27 = 1620 cu inches
