Triangular Prism Surface Area Concepts

The video tutorial covers the surface area of triangular prisms, explaining the components such as bases and lateral faces. It provides formulas for calculating surface area and demonstrates the process through example problems. The tutorial concludes with an assignment for students to complete independently.

What is the formula for the area of a triangle used in calculating the surface area of a triangular prism?

• Base times height

• Base minus height

• Base times height divided by two

• Base plus height

Which faces make up the lateral surface area of a triangular prism?

• Two triangular bases

• Four square faces

• One circular face

• Three rectangular faces

What is the first step in finding the lateral surface area of a triangular prism?

• Find the perimeter of the base

• Calculate the area of the base

• Add the areas of all faces

• Measure the height of the prism

How do you find the perimeter of the base of a triangular prism?

• Divide all sides

• Multiply all sides

• Add all sides

• Subtract all sides

In the example, what is the height of the triangular prism if the base is 5 and the unused side is 10?

• 5

• 15

• 20

• 10

What is the total surface area of the triangular prism in the example if the lateral surface area is 300 and the base area is 30?

• 330

• 360

• 420

• 390

Which part of the triangular prism is not used when calculating the height in the example?

• The hypotenuse

• The base

• The lateral face

• The unused side

What should students do to ensure they understand the formula for total surface area?

• Show their work

• Guess the answer

• Memorize the formula

• Ignore the formula

What is the due date for the asynchronous homework mentioned in the video?

• 5/10

• 5/15

• 5/12

• 5/20

What is the significance of the hash marks on the triangle in the example?

• They highlight the hypotenuse

• They indicate the base

• They mark equal sides

• They show the height
