There are 4 quarts in a gallon so the amount used can be shown as 4 1/4, or 4.25 so to find out how much gas is left in the tank you simply subtract 4.25 from 20.
20-4.25
=15.75
There is 15.75, or 15 3/4, gallons of gasoline left in the tank.
Answer:
Volume = 11 1/4 feet cubed
90 cubes can be added to fill the prism.
Step-by-step explanation:
(L)(W)(H) = volume
(2 1/2)(3)(1 1/2) = 11 1/4 ft cubed
1 cube is 1/2 a foot so 2 1/2 ft is 5 cubes, 3 ft is 6 cubes, and 1 1/2 ft is 3 cubes.
(5)(6)(3) = 90 cubes
