A waste oil tank is 5 feet wide and 20 feet long, the empty tank on your truck holds 5000 gallons.
If 7.48 gallons are in every cubic foot, what is the maximum depth the oil can be to completely fit into your truck?
:
Find the volume of the truck tank: 5000/7.48 = 668.45 cu/ft
:
Let d = the depth of the oil in the truck
5 * 20 * d = 668.45
100d = 668.45
d = 668.45/100
d = 6.6845 ft, which is 6 + .6845*12 = 6 ft 8 inches
