Understanding Surface Area of a Triangular Prism

The video tutorial explains how to calculate the lateral and total surface area of a triangular prism. It begins by defining lateral surface area and its significance. The tutorial then demonstrates the calculation of lateral surface area using the perimeter of the base and height, and offers alternative methods for understanding the concept. Finally, it covers the calculation of total surface area by adding the areas of the base and top to the lateral surface area.

What does the term 'lateral' refer to in the context of surface area?

• The top and bottom surfaces

• The side surfaces

• The entire surface area

• The base surface

How can you visualize the lateral surface area of a triangular prism?

• By rotating it on its top

• By laying it flat on its side

• By standing it up on its base

• By flipping it upside down

What is the formula for calculating the lateral surface area of a triangular prism?

• Perimeter of the base times height

• Base area times height

• Length times width

• Base times height divided by two

What is the perimeter of the base of the triangular prism in the example?

• 18

• 16

• 20

• 15

How is the lateral surface area calculated using individual panels?

• By dividing the total area by the number of sides

• By adding the areas of the top and bottom

• By multiplying the base area by the height

• By calculating the area of each rectangle and adding them

Why is it suggested to understand the formula rather than memorize it?

• Because the formula is incorrect

• Because understanding helps in applying it to different problems

• Because memorization is not allowed

• Because it is too complex to memorize

What is the height used in the calculation of the lateral surface area?

• 8

• 3

• 7

• 5

What additional areas must be added to the lateral surface area to find the total surface area?

• The area of the sides only

• The area of the top only

• The area of the base only

• The areas of the top and bottom

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

• 126 square units

• 150 square units

• 180 square units

• 200 square units

What is the area of one triangular base in the example?

• 12 square units

• 24 square units

• 36 square units

• 48 square units
