How to Find the Surface Area of Rectangular Prisms

The video tutorial explains two methods to find the surface area of a rectangular prism: using 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 a mathematical equation to quickly determine the surface area. Both methods are demonstrated with step-by-step instructions, ensuring viewers can confidently apply either technique.

What is the first step in finding the surface area of a rectangular prism using the net method?

• Draw a diagram of the prism

• Calculate the volume of the prism

• Unfold the prism into a net

• Measure the height of the prism

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

• Add the length and width

• Subtract the width from the length

• Multiply the length by the height

• Multiply the length by the width and then by two

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

• 122 inches squared

• 100 inches squared

• 150 inches squared

• 200 inches squared

In the formula method, what does '2B' represent?

• Two times the area of the base

• Two times the volume of the prism

• The height of the prism

• The perimeter of the base

What is the final step in calculating the surface area using the formula method?

• Divide the total by two

• Add the results of the base area and perimeter calculations

• Multiply the base area by the height

• Subtract the perimeter from the area
