And Good Evening everyone,
Today we are moving onto Volume of Pyramids.
Just like volume of prisms, volume of pyramids is the space inside the 3-D figure. Remember a prism maybe a cereal box and the volume of the box is the cereal inside??? Well, we have much the same with pyramids, but DIFFERENT! What is that difference????? This is a question you need to think about.
Pyramids are named by the base shape (polygon). So you could have a square pyramid if the base is a square- what would you call a pyramid with a triangle base?
The height of the pyramid is always from the tip of the vertex to the base and it forms a right angle. So be aware of looking for the height from inside the pyramid.
The shortcut - formula - is volume= 1/3 BH -
why would it be that?
To think about this, you may recall that a triangular prism is half of a rectangular prism- so....
A Pyramid of GIRLS!
