Volume of Prisms & Pyramids

Volume of Prisms & Pyramids

By Jamie McGuinn

Volume: the amount of space it takes to fill a 3D object; the capicity or amount it holds; l*w*h

​

• ​2 parallel and congruent bases

• surrounding faces are rectangles

​​Prisms:

​

​

• 1 base

• surrounding faces are triangles​

​​Pyramids:

​

​Volume = area of the base x height of prism

​​Prisms: V = Bh

​

​Note: Because you are multiplying all 3 dimensions together, the units will be cubed.
