Anyone good at Math?

BUT that would mean that the lenght wasn't 7 times the height...

length isn't 7h. its 7+h, reread the problem. heres my work

h(3h)(7+h)=108

3h^3+21h^2=108

h^3+7h^2-36=0

solve for zero and you have h=-6, h=-3, h=2.

first two are impossible dimensions so only answer left is h=2. Double check it works (2)(3[2])(7+2)=108 and you have the answer.
