Formula for total surface area of a prism

The lateral surface area of a prism is the sum of the areas of its lateral faces. The total surface area of a prism is the sum of the areas of its lateral faces and its two bases.

To work out the surface area of a prism, you work out the area of each face and add them all together. Sketching each face of the prism and labelling its dimensions can help to structure the solution. Below are a few examples of prisms with their component faces. If we inspect a cuboid, we can see that the prism is made up of 6 rectangular faces. It specifically has 3 pairs of congruent faces not all prisms have this property as the opposing faces are the same size. To calculate the surface area of the cuboid, we need to calculate the area of each face, and then add them together. Now that we know the area of each face, the surface area of the prism is the sum of these values.

Formula for total surface area of a prism

The surface area, also known as the total surface area TSA of a prism, is the total space occupied by its flat faces. The surface area is measured in square units such as m 2 , cm 2 , mm 2 , or in 2. The total surface area of a prism is the combined area of the 2 bases and the areas of the lateral faces. However, there are specific formulas to calculate the surface area of different prisms. They are given below:. Find the total surface area of a triangular prism whose base edges are 4 cm, 4 cm, 3 cm, height is 3. Find the total surface area of a hexagonal prism whose base edge is 3 cm, apothem is 2. Find the total surface area of a rectangular prism with a length of 7 cm, a width of 4 cm, and a height of 5 cm. Your email address will not be published.

Formula for total surface area of a prism

In mathematics, a prism is an essential member of the polyhedron family and is defined as a three-dimensional shape having two identical polygons facing each other that are connected by rectangular or parallelogram faces laterally. The identical polygons can be triangles, squares, rectangles, pentagons, or any other n-sided polygon and are called the bases of the prism. The other faces of a prism are parallelograms or rectangles. There are two kinds of prisms based on the type of the polygonal base, namely a regular prism and an irregular prism. Based on the alignment of the bases, there are two kinds of prisms, namely, the right prism and an oblique prism.

A prism with a pentagonal base is referred to as a pentagonal prism. Let us substitute the value of the base area as 2B in the surface area of the prism formula. The paint that Frank wants to use covers 10 square metres per litre. The area of surfaces of prisms is measured in squared centimeters, meters, feet cm 2 , m 2 , ft 2 , etc. The measurements that we have used are in m so the surface area of the prism is 6. What is the area of surfaces of prisms? An illustration of a rectangular prism, StudySmarter Originals The total surface area of a rectangular prism is: Twice the sum between the product of the base and the height of the rectangular base and the product of the height of the prism and the sum of the base and the height of the rectangular base. A prism has two kinds of surface areas, namely the lateral surface area and the total surface area. Let us look at some examples. Terms and Conditions. You are advised to try as many examples as possible to increase your competence in solving problems on the surface area of prisms.
