To find the surface area of the can, we need to find the area of the two circular ends and the area of the rectangular side.
The area of one circular end is (pi)(r^2), where r is the radius. In this case, the radius is half of the diameter, so the radius is 6/2 = 3 inches.
The area of one circular end is (3.14)(3^2) = 28.26 square inches.
Since there are two circular ends, the total area of the circular ends is 2(28.26) = 56.52 square inches.
The area of the rectangular side is the height multiplied by the circumference of the circular end. The circumference of a circle is 2(pi)(r), so the circumference of the circular end is 2(3.14)(3) = 18.84 inches.
The area of the rectangular side is (18.84)(4) = 75.36 square inches.
Adding the area of the circular ends and the area of the rectangular side, the total surface area of the can is 56.52 + 75.36 = 131.88 square inches.
Therefore, 131.88 square inches of paper will be needed for the label.
