To find the total surface area of the can, we need to find the surface area of the curved part (cylinder) and the surface area of the top and bottom (two circles).
The formula for the surface area of a cylinder is 2πrh, where r is the radius and h is the height.
Given that the diameter is 6 inches, the radius is 6/2 = 3 inches.
Using the formula, the surface area of the curved part is 2 * 3.14 * 3 * 4 = 75.36 square inches.
The formula for the surface area of a circle is πr^2.
Using the formula, the surface area of each circle is 3.14 * 3^2 = 28.26 square inches.
Since there are two circles (top and bottom), the total surface area of the circles is 2 * 28.26 = 56.52 square inches.
Adding the surface area of the curved part and the circles, we get a total surface area of 75.36 + 56.52 = 131.88 square inches.
Therefore, 131.88 square inches of paper will be needed for the label on the outside of the can.
