the volume of the rectangular prism is
... cubic inches.

Explanation:

Step1: Recall volume formula

The volume $V$ of a rectangular prism is $V = l \times w \times h$, where $l$ = length, $w$ = width, $h$ = height.

Step2: Substitute given values

$l = 2\frac{1}{2}$ in, $w = 1$ in, $h = 3$ in. First convert $2\frac{1}{2}$ to an improper fraction: $2\frac{1}{2} = \frac{5}{2}$.
Expression: $V = \frac{5}{2} \times 1 \times 3$

Step3: Calculate the product

Multiply the values together.
Expression: $V = \frac{5 \times 1 \times 3}{2} = \frac{15}{2} = 7.5$

Answer:

7.5 or $\frac{15}{2}$ cubic inches
