An oblique rectangular prism is stated as a prism in which faces are not perpendicular to one another.A rectangular prism with all sides the same is called a cube.The unit of measurement of the area of the rectangular prism is square units.The total surface area of a solid is the sum of the areas covered by all the faces or surfaces enclosing the object.Step 4: The units calculated are in square units. Step 3: Utilize the formula for the lateral surface area or the total surface area. Step 2: Once the dimensions are made the same, one can calculate the lateral surface area or the total surface area as per the condition given. Step 1: The given dimensions of the rectangular prism must be in same units if not then make same. The surface area of a rectangular prism can be found by using the following steps: How To Calculate the Surface Area of a Rectangular Prism Lateral surface area of a rectangular prism= 2(l+b) h The formula for the lateral surface area of a rectangular prism is, ![]() This does not include the area of the bases. The lateral surface area of a rectangular prism can be calculated by finding the sum of all the lateral faces of the prism. Lateral Surface Area of a Rectangular Prism Total surface area of a rectangular prism = 2(lb+bh+hl) The formula for the surface area of a rectangular prism is, The total surface area of a rectangular prism can be found by calculating the total area of all its six faces. Total Surface Area of a Rectangular Prism Lateral surface area of a rectangular prism.Total surface area of a rectangular prism.To find the surface area of a rectangular prism, we need to find the sum of the areas of all the faces of the prism.įurther, a rectangular prism is divided into two types: Surface Area Of A Rectangular Prism: Formula Hence, both the bases of the rectangular prism must be rectangles as well. It consists of six faces and all are rectangular in shape. Find lateral surface area and total surface area.The total area or region covered by all the faces of a rectangular prism is defined as the surface area of a rectangular prism. 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. The height of the prism is the common edge of two adjacent side faces.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. 3 Solved Examples Prism Formula What is Prism?
