Surface area of pyramids quick check unit 8
lesson 4

Answer 1

To find the surface area of a pyramid, you need to calculate the sum of the areas of all its faces. The formula for the surface area of a pyramid depends on the shape of its base.

If the base is a triangle, the formula is:
Surface Area = Base Area + (1/2) * Perimeter of Base * Slant Height

If the base is a rectangle or square, the formula is:
Surface Area = Base Area + 2 * (Area of Each Triangle Face)

If the base is a polygon with n sides, the formula is:
Surface Area = Base Area + (1/2) * Perimeter of Base * Slant Height * n

Make sure to substitute the appropriate values into the formula to calculate the surface area of the specific pyramid you are working with.
