Surface Area of Rectangular Prisms

The video tutorial explains two methods to find the surface area of rectangular prisms: by creating a net and using a formula. The net method involves unfolding the prism and calculating the area of each face, while the formula method uses the base area and perimeter to find the surface area. Both methods are demonstrated with step-by-step instructions, and the video aims to build confidence in solving such problems.

What are the two methods mentioned for finding the surface area of a rectangular prism?

• Using a compass and a protractor

• Using a net and a formula

• Using a ruler and a calculator

• Using a graph and a chart

What is the first step in finding the surface area using a net?

• Folding the prism into a cube

• Unfolding the prism into a net

• Drawing the prism on paper

• Measuring the angles of the prism

How do you calculate the area of the blue faces in the net method?

• Multiply length by width and divide by two

• Add length and width, then multiply by two

• Multiply length by width and multiply by two

• Subtract width from length and multiply by two

What is the total surface area of the rectangular prism using the net method?

• 144 inches squared

• 122 inches squared
