How to Find Surface Area of a Rectangular Prism?

Let us go through an example to understand the concept of calculating the surface area of a rectangular prism.

Example: Calculate the surface area of a rectangular prism if its height is 15 units and the length and breadth of the base are 10 units and 6 units, respectively.

Step 1: Note the dimensions of the given rectangular prism. In the given example, the length and breadth of the rectangular prism’s base are 10 units and 6 units, respectively, and its height is 15 units.

Step 2: We know that the surface area of a rectangular prism is equal to 2(lb + bh + lh) square units. Now, substitute the given values of length, breadth, and height in the formula.

Step 3: So, the surface area of the rectangular prism is calculated as, A = 2× (10 × 6 + 6 × 15 + 10 × 15) = 600 sq. units.

Using the above steps Surface Area of a Rectangular Prism is found.

Surface Area of a Rectangular Prism is the area covered by all the surfaces of the rectangular prism. A rectangular prism is a 3-D geometrical figure with four lateral faces with two congruent and parallel faces. A rectangular prism has a total of six faces where the opposite faces are identical, i.e., a rectangular prism has three pairs of identical faces. The dimensions of a rectangular prism are length, width, and height. It has a total of six faces, twelve edges, and eight vertices.

In this article, we will learn about the Surface Area of a Rectangular Prism (Right Rectangular Prism), the Lateral Surface Area of a (Right) Rectangular Prism, the Total Surface Area of a (Right) Rectangular Prism, and others in detail.
