The formula to compute the area for a solid oblique pyramid which has a regular pentagonal base is V=1/3*h*B where "h" represent the height and "B" for the area of the base.
In the given problem area is given which is equal to 8ft² and height is 2.16. Then we can solve for the volume such as shown below:
V=1/3*2.16*8
V=5.76 ft³

Answer:
Volume of the pyramid:
V = 1/3 · B · h
B = 8 ft²
tan 30° = height / 7√3
1/√3 = height / 7√3
height = 7 ft
V = 1/3 · 8 · 7 = 18.67 ft³ ≈ 19 ft³
Answer : D ) 19 ft³
