Question

what is the volume of this triangular pyramid? cubic feet

Explanation:

Step1: Find base area

The base is a triangle with base 7 ft and height 6 ft.
Area of base = $\frac{1}{2} \times 7 \times 6 = 21$ sq ft.

Step2: Calculate volume

Volume of pyramid = $\frac{1}{3} \times$ base area $\times$ height. Height = 4 ft.
Volume = $\frac{1}{3} \times 21 \times 4 = 28$.

Answer:

28 cubic feet
