ANSWER
The volume of the mailing tube is 678.6 square inches to the nearest tenth.
EXPLANATION
The volume of a cylinder is calculated using the formula;
[tex]V=\pi \: {r}^{2} h[/tex]
Since the mailing tube is in the form of a cylinder, we use this formula to find its volume.
We substitute h=24 and r=3 to obtain,
[tex]V=\pi \times {3}^{2} \times 24[/tex]
[tex]V=216\pi {in}^{2} [/tex]
[tex]V=678.6{in}^{2} [/tex]
