Understanding Lateral Surface Area

What is the formula used to calculate the lateral surface area of a prism?

• Perimeter of the base plus height

• Perimeter of the base times height

• Area of the base times height

• Two times the area of the base

In the example of the triangular prism, what is the perimeter of the base?

• 12

• 10

• 8

• 15

How is the lateral surface area of a regular pyramid calculated?

• Area of the base plus slant height

• One-half times the perimeter times the slant height

• Perimeter times height

• Area of the base times height

For a rectangular pyramid, how do you find the area of the triangles along the length?

• Base times slant height divided by two

• Perimeter times slant height

• Base times height

• Base plus slant height

What is the total lateral surface area of the rectangular pyramid example?

• 18.7 square feet

• 15.5 square feet

• 25.3 square feet

• 20.9 square feet
