11.5. Pyramids http://www.ck12.org
Aregular pyramidis a pyramid where the base is a regular polygon. All regular pyramids also have aslant height,
which is the height of a lateral face.
Surface areais a two-dimensional measurement that is the total area of all surfaces that bound a solid.Volumeis a
three-dimensional measurement that is a measure of how much three-dimensional space a solid occupies.
Guided Practice
- Find the area of the regular triangular pyramid.
- If the lateral surface area of a square pyramid is 72f t^2 and the base edge is equal to the slant height, what is the
length of the base edge? - Find the area of the regular hexagonal pyramid below.
- Find the volume of the pyramid.
