Question

find the total surface are of a regular pyramid with a square base of each edge of the base measures 16 inches the slant height of a side is 17 inches and the altitude is 15 inches​

Answer 1

Answer:

The lateral surface area of a regular pyramid is the sum of the areas of its lateral faces.

The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base.

The general formula for the lateral surface area of a regular pyramid is L.S.A.=12pl where p represents the perimeter of the base and l the slant height.

Step-by-step explanation:

Example 1:

Find the lateral surface area of a regular pyramid with a triangular base if each edge of the base measures 8 inches and the slant height is 5 inches.

The perimeter of the base is the sum of the sides.

p=3(8)=24  inches

L.S.A.=12(24)(5)=60  inches
