Answer
The volume of the rectangular ice chest is $7\frac{7}{8}$ ft.
Work Step by Step
The volume of a rectangular prism is $V = l \times w \times h$, where $l$ is the length, $w$ is the width, and $h$ is the height.
The dimensions of the rectangular ice chest are $3$ ft by $1\frac{1}{2}$ ft by $1\frac{3}{4}$ ft.
$V = 3 \times 1\frac{1}{2} \times 1\frac{3}{4} = 7\frac{7}{8}$
The volume of the rectangular ice chest is $7\frac{7}{8}$ ft.
