--->
---> equation C (convert ft to in)
substitute equation B and equation C in equation A

solve for L
Apply distributive property



Solve the cubic equation by graphing
using a graphing tool
The solution is L=88.95 in
see the attached figure
Find the height of the aquarium H

substitute the value of L

Find the value of W
