We need to calculate the lateral area of the cans, so:


\text{Lateral area=}\pi\cdot6in\cdot5in\approx94.2in^2

Each can has an area of 94.2 inches squared.

We only know the area of the sheet, so we can calculate the total cans as:


\begin{gathered} \text{Sheet area = 3750 in}^2 \\ Total\text{ cans=}\frac{Sheet\text{ area}}{Lateral\text{ area}}=(3750)/(94.2)=39.8\Rightarrow Total\text{ cans = 39} \end{gathered}

The total cans is 39.
