Question

1. a rectangular prism has a top face with an area of $20\\ \text{ft}^2$ and a height of 5 ft. what is the volume of this rectangular prism?

Explanation:

Step1: Recall volume formula for prism

The volume \( V \) of a prism is given by \( V = \text{Base Area} \times \text{Height} \). Here, the top face area equals the base area, so we use \( 20 \, \text{ft}^2 \) as the base area.

Step2: Substitute values and calculate

Substitute base area \( = 20 \, \text{ft}^2 \) and height \( = 5 \, \text{ft} \) into the formula.
\( V = 20 \times 5 \)

Answer:

\( 100 \, \text{ft}^3 \)
