Surface Area of a Prism Calculator
Top

A prism is a n-sided polyhedron prepared of an n-sided polygonal base, a translated copy and n faces combination consequent sides. The cross-sections corresponding to the base faces are similar. A prism might be having a triangular base (triangular prism), rectangular base (rectangular prism), and so on.

Surface Area of a Prism Calculator (or Surface Area of a Rectangular Prism Calculator or Surface Area of a Triangular Prism Calculator) is used to calculate the Surface area when the value of the area of the base, perimeter and height of the prism is entered.

## Step by Step Calculation

Step 1 :

Observe the shape of the base of the given prism and its $\frac{height}{length}$.

Step 2 :

Find the area of the base according to the applicable formula

Step 3 :

Find perimeter of the base

Step 4 :

Apply the formula,

Surface Area of prism = (Perimeter of base × height) + (Area of the base × 2)

## Example Problem

1. ### Find the area of the prism of height 6cm with an equilateral triangular base having side 3cm

Step 1 :

Perimeter of the base = 3 × side = 3 × 3 = 9 cm
