Question

what is the volume of this triangular pyramid? 11 m 15 m 12 m

Explanation:

Step1: Recall volume formula for pyramid

Volume = $\frac{1}{3} \times$ base area $\times$ height

Step2: Calculate base area (triangle)

Base area = $\frac{1}{2} \times 15 \times 11 = 82.5$ $m^2$

Step3: Substitute into volume formula

Volume = $\frac{1}{3} \times 82.5 \times 12$

Step4: Compute final volume

Volume = $82.5 \times 4 = 330$ $m^3$

Answer:

330 cubic meters
