10-Surface Area of Pyramids and Cones Author: Mike Created Date: 7/16/2012 1:25:14 PM
Students find the surface area of three-dimensional objects whose surface area is composed of triangles and quadrilaterals, specifically focusing on pyramids. They use polyhedron nets to understand that surface area is simply the sum of the area of the lateral faces and the area of the base(s).
How can you fi nd the surface area of a pyramid? Even though many well-known pyramids have square bases, the base of a pyramid can be any polygon. Triangular Base. Vertex Lateral face Slant height Base. Square Base. Hexagonal Base. 1 ACTIVITY: Making a Scale Model. Work with a partner. Each pyramid has a square base.
The surface area of a hexagonal pyramid is given by 4752 square inches and the side length is 33 inches and apothem length 11 inches. Find the slant height of the hexagonal pyramid.
Surface area of a Hexagonal Pyramid. Find the surface area of a hexagonal pyramid? (a=apothem, b=breadth, s=slant height).
