Answer:
360 ft³
Step-by-step explanation:
The formula of a volume of a pyramid:
[tex]V=\dfrac{1}{3}BH[/tex]
B - area of a base
H - height
In the base we have the rectangle 12ft × 6ft.
Therefore
[tex]B=(12)(6)=72\ ft^2[/tex]
H = 15 ft
Substitute:
[tex]V=\dfrac{1}{3}(72)(15)=\dfrac{(72)(15\!\!\!\!\!\diagup^5)}{3\!\!\!\!\diagup_1}=(72)(5)=360\ ft^3[/tex]
