Learning to find the surface area of a rectangular prism

The video tutorial explains how to find the lateral surface area of a rectangular prism. It begins by identifying the six sides of the prism and emphasizes that opposite sides have the same dimensions and area. The teacher demonstrates calculating the surface area by finding the areas of the front, back, base, top, right, and left sides, then multiplying by two. The example uses specific dimensions to illustrate the process, resulting in a total surface area of 136 square inches.

What is the total number of sides in a rectangular prism?

• Four

• Six

• Ten

• Eight

When calculating the surface area of a rectangular prism, why do we multiply the area of each pair of opposite sides by two?

• Because they have different dimensions

• Because they have the same dimensions

• To account for the top and bottom

• To simplify the calculation

Which of the following represents the area of the base and top of a rectangular prism if the dimensions are 8 and 4?

• 3 * 4

• 8 * 4

• 3 * 8

• 4 * 4

What is the final calculated surface area of the rectangular prism in the example?

• 136 inches squared

• 148 inches squared

• 124 inches squared

• 160 inches squared

In the context of the video, what unit of measurement is used for the dimensions of the rectangular prism?

• Feet

• Inches
