#FORMULA OF TRIANGULAR PRISM SURFACE AREA HOW TO#

This online demonstration of an adjustable triangular prism is a good example to see the relationship between the object's height, lengths, and surface area. The formula for surface area of a triangular prism is actually a combination of the formulas for its triangular bases and rectangular sides. So calculate the triangle part of the surface area now: There are two triangles for its base (Front + Back). We'll first divide up the steps to illustrate the concept of finding surface area, and then we'll give you the surface area of a triangular prism formula.įind the surface area of the following triangular prism. Let's try to find the surface area of a triangular prism and take a look the prism below. You can easily see how the surface area requires all the sides' area to be found and how it represents the total area surrounding the 3D figure. A good way to picture how this works is to use a net of a 3D figure. In order to find the surface area, the area of each of these sides and faces will have to be calculate and then added together. So what is surface area?ģD objects have surface areas, which is the sum of the total area of the object's sides and faces.

How to find the surface area of a triangular prismĪrea helps us find the amount of space contained on a 2D figure. Therefore, since the solid has two bases (the bottom one and the top one), the surface area of a rectangular prism formula is as follows: surfacearea 2 × basearea + lateral.

On the other hand, Al denotes the lateral area, meaning the total area of the four lateral faces. Today we're going to focus on triangular prisms, that is, a prism with a polygonal base that has 3 sides. Note that Ab denotes the surface area of a single base of our prism.

For example, we can have pentagonal prisms and square prisms. In the formulas above, you can see the area of the base is part of the volume formulas: V l w h where A l w is the area of a rectangle. The naming convention for prisms is to name the prism after the shape of its base. If it's connected by parallelograms, it's called an oblique prism. If it's connected with rectangular surfaces (its sides are made of rectangles), it's called a right prism. They have polygonal bases on either sides which are connected to each other by rectangular or parallelogram surfaces. Prisms are 3D shapes made of surfaces that are polygonal. To understand what a triangular prism is, let's start with the definition of prisms.
