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. Today we're going to focus on triangular prisms, that is, a prism with a polygonal base that has 3 sides. For example, we can have pentagonal prisms and square prisms. 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.

Shodor's academic program efficiently guides participants from excitement to experience to expertise through computational explorations, research opportunities, and service. Resources and materials offered to these instructors are available free of charge from Shodor's website and are largely developed by Shodor student interns. Additionally, the National Computational Science Institute (NCSI) provides nation-wide workshops portraying resources and instructional ideas to middle school, high school, and undergraduate instructors for use in the classroom. Student development of numerical models and simulations integrated with core curriculum provides an opportunity to gain practical experience in computational science. On a mission to transform learning through computational thinking, Shodor is dedicated to the reform and improvement of mathematics and science education through student enrichment, faculty enhancement, and interactive curriculum development at all levels.
