To find the surface area of a single cube, you calculate the area of each face (6 faces) and add them together. Each face has an area of 1 cm x 1 cm = 1 cm². Therefore, the surface area of one cube is 6 cm². If the stack consists of n cubes, the total surface area would be 6n cm².
The total surface area of a 100 by 100 cm cube is 60,000 square centimeters. Each smaller cube has a surface area of 6 square centimeters for a total of 6,000,000 square centimeters. This is a gain of 5,940,000 square centimeters.
You need three measures of length to determine the surface area - the length, width and height.
