Answer:
volume ≈ 75.8 ft³(nearest tenth of a cubic foot)
Step-by-step explanation:
A square base pyramid has the base of the pyramid as a square. The lateral faces are triangular. The volume of a square base pyramid is the product of the base area and the height of the pyramid divided by 3. Mathematically, it is expressed below
The volume of a square base pyramid = 1/3Bh
where
B = base area
h = height of pyramid
B = 19. 6 ft²
h = 11. 6 ft
volume = 1/3 × B × h
volume = 1/3 × 19.6 × 11.6
volume = 227.36/3
volume = 75.7866666667
volume ≈ 75.8 ft³(nearest tenth of a cubic foot)
