Triangular Prism Tutorial

Prism Definition:

A prism is a polyhedron made of an n-sided polygonal base, a translated copy, and n faces joining corresponding sides.

Triangular Prism Definition:

A Triangular Prism is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides.

Triangular Prism Example :

Case 1:

Find the surface area and volume of a triangular prism with the given altitude 2, base 3, height 4 and the sides 1, 2, 3.

Step 1:

Find the area of the base. Area of the base(A) = ½ * a * b = 0.5 * 2 * 3 = 3.

Step 2:

Find the perimeter of the base. Perimeter of the base(P) = s1 + s2 + s3 = 1 + 2 + 3 = 6.

Step 3:

Find the surface area of prism. Surface Area of Prism = ab + Ph = (2 * 3) + (6 * 4) = 6 + 24 = 30.

Step 4:

Find the volume of prism. Volume of Prism = Ah = 3 * 4 = 12. The above example will clearly illustrates how to calculate the Volume, Surface Area, Perimeter of a Triangular Prism manually.
