Find the volume of the pyramid to the nearest tenth. Estimate to check whether the answer is reasonable.
V = 13 Bh Use the formula.
B = 5 · 7 = 35 Find the area of the rectangular base.
V = 13 · 35 · 4 Substitute for B and h.
V ≈ 46.7 ft3
Estimate
5 ft 7 ft
4 ft
Multiply.
V = 13 · 30 · 5 Round the measurements.
V = 50 ft3 The answer is reasonable.
