surface area of triangular prisms formula

Find lateral surface area and total surface area.

The base of a triangular prism is ΔABC, where AB = 6 cm, BC = 8 cm and ∠B = 90. Q 1: What will be the surface area of a triangular prism if the apothem length, base length, and height are 5 cm, 10 cm, and 18 cm respectively? 1] Rectangular PrismĪ Rectangular Prism has 2 parallel rectangular bases and 4 rectangular faces.Ī triangular prism has 3 rectangular faces and 2 parallel triangular bases.Ī pentagonal prism has 5 rectangular faces and 2 parallel pentagonal bases.Ī hexagonal prism has six rectangular faces and two parallel hexagonal bases. Prisms are of different types, which are named according to their base shape. Remember, we can use a formula to calculate the area of a pair of faces. Surface Area of Triangular Prisms First, we know that we need to nd the area of the two triangular faces. The height of the prism is the common edge of two adjacent side faces. rectangles, so we’ll have to proceed differently here to nd a formula for surface area.With every lateral face, one edge in common with the base and also with the top.

Each face is a parallelogram except base and top.The base and top are parallel and congruent.The volume of a prism =Base Area× Height.The surface area of a prism = (2×BaseArea) +Lateral Surface Area.In some cases, it may be a parallelogram. The Prism Formula is as follows,

The lateral faces are mostly rectangular. Lateral faces join the two polygonal bases. In physics (optics), a prism is defined as the transparent optical element with flat polished surfaces that refract light. In mathematics, a prism is a polyhedron with two polygonal bases parallel to each other. Let us now study about prism formula in detail. We can use the concept of prism in both mathematics and science as well. A prism is a solid bounded by a number of plane faces its two faces, called the ends, are congruent parallel plane polygons and other faces, called the side faces, are parallelograms.
