A prism is a 3-D object where the end faces are 2 parallel congruent polygons. A triangular prism is a prism with triangle bases.

Volume (V) is the amount of space a three-dimensional (3-D) figure occupies. Volume is expressed in cubed units such as mm³, yd³, or ft³.

The volume formula for triangular prisms is Volume = Area of the triangle base × Length.

h = height b = base l = length   Volume = Area of the triangle base × length V = (base)(height) × length   = bh × l

Example 1:

Find the volume of the triangular prisms given. Answer with proper units. To represent m³, use cu m. Sample answer: 5 cu m
volume =

V	=	bh × l
	=	(7 in)(6 in) × 5 in
	=	105 in3

The answer is volume =
