Question

what is the volume of this rectangular pyramid?
3 ft
4 ft
5 ft
cubic feet

Explanation:

Step1: Find base area

The base is a rectangle, so area is length × width.
$\text{Base Area} = 4 \times 5 = 20$ square feet

Step2: Apply pyramid volume formula

Volume of rectangular pyramid is $\frac{1}{3} \times \text{Base Area} \times \text{Height}$.
$\text{Volume} = \frac{1}{3} \times 20 \times 3$

Step3: Calculate final volume

Simplify the expression.
$\text{Volume} = 20$

Answer:

20 cubic feet
