Given:
Width=+W+=%284x%2B3%29ft
Length=+L+=+%285x-2%29+ft
Hight=+H+=+%283x%2B2%29ft
Find:
Volume=V
V+=+W%2AL%2AH
V+=+%284x%2B3%29ft+%2A%285x-2%29+ft+%2A%283x%2B2%29ft+
V+=+%284x%2B3%29%2A%285x-2%29+%2A%283x%2B2%29ft%5E3+…………multiply first two binomials
V+=+%2820x+-+8x+%2B+15x+-+6%29%283x%2B2%29ft%5E3
V+=+%2827x+-+6%29+%2A%283x%2B2%29ft%5E3+………now multiply these two binomials
V+=+%2881x+%2B+54x+-+18x+-+12%29%283x%2B2%29ft%5E3
V+=+%28117x-+12%29+ft%5E3+………
