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
