## How To Find The **Surface Area Of A Prism**?

Let's look at the geometric characteristics of a prism. But first, please review the definition of Surface Area Of Three-Dimensional Shapes.

- A prism is a two dimensional triangle with height; with height it becomes a three dimensional shape.
- The trick to determining the surface area of a prism to identify
the type of triangle in the base and compute its surface area: Acute Triangle Area, Obtuse Triangle Area, Equilateral Triangle Area,
Isosceles Triangle Area,
Right Triangle Area, and Scalene Triangle Area. This
result will be part of the surface area of a prism formula; from now on, let's call
this the base
**(B)**. Also keep in mind there are two base areas - top and bottom. - You will also need to know the Perimeter of base area. There are two options: (1) determine the type of triangle the base and use the perimeter calculator, (2) The perimeter of the base triangle is equal to the sum of the sides P1 + P2 + P3.
- Special note, the Base, the perimeter and height of a prism must be greater than zero.

**Surface Area Of A Prism Formula**

Surface Area = (Base + Base) + ((P1 + P2 + P3) * Height) =

Surface Area = (B + B) + (P × H) =

Surface Area = (2 × B) + (P × H)
