Volume of a Triangular Prism

Welcome to the wonderful world of 3-D measurement!  3-D stands for three dimensional, as in geometric shapes that have a length, width, and a height.  These shapes are not flat, like two dimensional shapes.  Instead, they jump off of the page, right at  you.

How to find the volume of a triangular prism?  In order to figure out how much stuff fits into a 3-D shape, we calculate the volume of that shape.  To  find the volume of a triangular prism, we must find the area of its base, which is a triangle, of course.  Then we multiply that area times  the height of the shape.

For those students that prefer formulas, here it is:

Volume (triangular  prism) =  (1/2 x length x width) x height

Parents, students, and teachers, enjoy these free volume worksheets.  As usual, each worksheets comes with an answer key and is completely customizable.  Plus, they’re always free!

Volume of a Triangular Prism Worksheet 1 – Here is a nine problem math worksheet that helps you practice finding the volume of a triangular prism. You will be given the length, width, and height of each prism. Simply find the area of the triangle at the bottom of the prism 1/2(length x width) then multiply that area times the height of the prism.
