An oatmeal box is shaped like a cylinder. Use a net to find the surface area S of the oatmeal box, rounded to the nearest tenth. Then find the number of square feet of cardboard needed for 1,500 oatmeal boxes, rounded to the nearest whole number. Use 3.14 for π.

(The radius is 4 inches, and height is 9 inches for the cylinder)

Given:

radius = 4 inches

height = 9 inches. cylinder

1500 oatmeal boxes needed to be made.

We need to find the area of the cylinder.

A = 2 π r h + 2 π r ²

A = 2 * 3.14 * 4in * 9 in + 2 * 3.14 * (4in) ²

A = 226.08 in ² + 6.28 * 16in ²

A = 226.08 in ² + 100.48 in ²

A = 326.56 in ²

Total area needed for 1,500 oatmeal boxes.

326.56 in² * 1,500 oatmeal box = 489,840 in²
