Answer:
162 ft^3
Step-by-step explanation:
volume = area of base * height
V = 22 1/2 ft^2 * 7 1/5 ft
Change the mixed numerals into fractions.
V = 45/2 ft^2 * 36/5 ft
Multiply the fractions.
V = 45/2 * 36/5 ft^3
Switch the denominators.
V = 45/5 * 36/2 ft^3
Simplify each fraction.
V = 9 * 18 ft^3
V = 162 ft^3
