Surface Area and Area of Shapes

The video tutorial explains how to calculate the surface area of a cube. It begins by defining surface area as the total area of all the cube's faces, which are all squares. The tutorial then demonstrates how to calculate the area of one face using the formula for the area of a square, length times width. With the length and width both being 12 inches, the area of one face is calculated as 144 square inches. Since a cube has six identical faces, the total surface area is found by multiplying the area of one face by six, resulting in 864 square inches.

What is the surface area of a shape?

• The length of its sides
