Exploring Adding and Subtracting Rational Expressions

The video tutorial covers the concept of surface area for prisms, focusing on rectangular and triangular prisms. It explains how to calculate surface area using both individual face measurements and net diagrams. The tutorial provides examples and practice problems to reinforce understanding, and introduces a general formula for calculating the surface area of any prism.

What is the surface area of a prism composed of?

• Only the area of the bases

• Only the area of the lateral faces

• The sum of the areas of the bases and lateral faces

• The product of the areas of the bases and lateral faces

How do you calculate the area of a base in a rectangular prism?

• Length times width

• Length plus width

• Width times height

• Length times height

In the example, what is the area of the lateral faces calculated using the net?

• 126 square units

• 30 square units

• 96 square units

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

• 144 square units

• 84 square units

• 126 square units

• 96 square units

How is the area of a triangle calculated?

• One half base times height

• Base divided by height

• Base plus height

• Base times height

What is the area of the lateral surfaces of the triangular prism in the example?

• 96 square units

• 72 square units

• 12 square units

• 84 square units

What is the total surface area of the triangular prism calculated in the example?
