Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V = [tex]\frac{1}{3}Bh[/tex], where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V = [tex]\frac{(12)(7)}{3}[/tex]
V = 28 ft³
