L = length
W = width
H = height
the top is 240 square inches the side 300 and the end 180
1) LW = 240
W = 240/L
2) LH = 300
H = 300/L
3) WH = 180
(240/L)(300/L) = 180 {substitute from equations 1 & 2}
L^2 = (240)(300)/(180) = 400
L = 20
Using this in equations 1 * 2, find W & H

x*y = 240 ; y*z = 300 ; x*z = 180
240 = (2 * 2) * 2 * 2 * 3 * 5
300 = (2 * 2) * 3 * 5 * 5
180 = (2 * 2) * 3 * 3 * 5
x = 12
y = 20
z = 15

L=8 W=10 H=30. Those should be the right numbers i am not sure if that is the right places that they go.
