The surface area of a soda can is calculated by measuring the height and the diameter. With these two known results, the area is calculated using 2πr^{2} for the ends of the can and πd for the circumference of the can multiplied by the height.

The surface area of a 12-ounce soda can measures 2.62 inches in diameter and 6.82 inches tall. The surface area of the ends of the can is calculated as follows: 2.62/2 = a radius of 1.31, r^{2} = 1.31 x 1.31 = 1.716, 1.716 x 3.142 = 5.392, 5.392 x 2 = 10.784 square inches. The surface area of the sides of the can is calculated as follows: 2.62 x 3.142 = 8.232, 8.232 x 6.82 = 56.142 square inches. The total surface area is 10.784 + 56.142 = 66.926 square inches.
