# Surface Area of a Triangular Prism Calculator

In general surface area is defined as the total area the surface of the object occupies. A triangular prism is a polyhedron which has the triangular base. It has 5 faces and 9 edges. Use our online surface area of a triangular prism calculator to efficiently calculate the total surface area occupied by the triangular based prism. Enter the triangle's sides, base, height, and prism height in the prism calculator to find the SA of the triangular prism.

In general surface area is defined as the total area the surface of the object occupies. A triangular prism is a polyhedron which has the triangular base. It has 5 faces and 9 edges. Use our online surface area of a triangular prism calculator to efficiently calculate the total surface area occupied by the triangular based prism. Enter the triangle's sides, base, height, and prism height in the prism calculator to find the SA of the triangular prism.

#### Formula:

Surface Area = ( Base × Height ) + ( ( Side1 + Side2 + Side3 ) × Prism Height )

### Example:

Find the surface area of triangular prism whose sides are equilateral with 4cm, the prism height is 3 cm, triangle base is 4 cm and triangle height is 12 cm.

#### Solution:

Surface Area = ( 4 × 12 ) + ( ( 4 + 4 + 4 ) × 3 )
= 84 cm2
