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