Answer:

V = 36 in³

Step-by-step explanation:

The volume of a rectangular prism is given by the formula V = l × w × h

Here our length is $9\frac{1}{2}$ , our width is 4, and our height is $4\frac{1}{2}$

Plugging in these values to our formula give us $V=(9\frac{1}{2})(4)(4\frac{1}{2})= 36$

V = 36 in³
