Answer:
144 in³
Step-by-step explanation:
The volume of a pyramid of base area A and height h is
V = (1/3)(A)(h).
Here,
V = (1/3)(6 in)²(12 in) = 144 in³
option (4)
To calculate the area of a triangle, multiply the base and the height, then divide the product by 2.
7*8=56
56/2=28
Area=28 feet squared
