Surface Areas of PyramidsSurface Areas of PyramidsObjective: To find the surface area of pyramids.

Surface Areas of PyramidsThe surface area (SA) of a three dimensional figure is the outer face or exterior boundary of the figure.

Surface Areas of PyramidsA pyramid is a three-dimensional figure with faces that meet at a common vertex.

vertexSurface Areas of PyramidsThe shape of the base determines the name of the pyramid.

Surface Areas of PyramidsA pyramid has at least three triangular sides, called lateral faces.

Surface Areas of PyramidsThe slant height is the distance from the vertex to the mid-point of a side of the base.

Surface Areas of PyramidsThere are two methods to find the surface area of a regular pyramid. 1. Formula2. Net

slant heightSurface Areas of PyramidsAs with prisms, the shape of the base determines the name of the pyramid.

Surface Areas of PyramidsThere are many types of pyramids. We will only be concerned with triangular pyramids and square pyramids.

Surface Areas of PyramidsAll pyramids that we will be working with will be regular pyramids, meaning the bases will either be a square or equilateral triangle.










Surface Areas of PyramidsFind the SA of regular pyramid. You can also construct a net to to find the SA of a pyramid.

Surface Areas of PyramidsFind the SA of regular pyramid.

To find the surface area by using a net the area of each section is added together, like a composite shape.
