How to Find Surface Area of a Rectangular Prism?

How to find surface area of a rectangular prism? A rectangular prism is a three-dimensional diagram with six rectangular faces. To find the surface area of a rectangular prism, we need to find the area of all six faces and add them together.

To find the area of each face, we need to multiply the length and width of that face. The length and width of each face are different, so we need to make sure we’re finding the right measurements for each one.

Once we have the areas of all six faces, we can add them together to get the total surface area of the rectangular prism.

What Is A Rectangular Prism?

A rectangular prism is a solid three-dimensional figure with six faces that are all rectangles. The opposite sides of a rectangular prism are parallel, and the angles between them are all 90 degrees.

A rectangular prism has two sets of parallel faces, so it is also called a parallelepiped. The length, width, and height of a rectangular prism are denoted by l, w, and h.

What Is The Surface Area Of A Rectangular Prism?

A rectangular prism is a solid geometric figure with six faces that are rectangles. The surface area of a rectangular prism can be found by adding the areas of all six faces.

To find the area of each face, multiply the length and width of the rectangle. The total surface area of a rectangular prism is the sum of the areas of all six faces.

The surface area of a rectangular prism is important to know when trying to find the amount of material needed to cover the outside of the figure. It can also be used in 3D printing to determine how much material is required to create an object.

Surface Area Of A Rectangular Prism Formula

A rectangular prism is a three-dimensional object with six faces that are rectangles. You can calculate the surface area of a rectangular prism by using the formula:

Surface Area = 2lw + 2lh + 2hw

Where: l is the length, w is the width, and h is the height. To find the surface area, you need to know all three dimensions.

How To Find The Surface Area Of A Rectangular Prism

A rectangular prism is a three-dimensional diagram with six rectangular faces. To find the surface area of a rectangular prism, we need to find the areas of all six faces and add them together.

To get the area of a rectangle, we multiply the length by the width. The length and width of each face of a rectangular prism are labeled. To find the surface area, we need to find the areas of all six faces and add them together.


The length of Face A is 4 inches and the width is 3 inches, so the area of Face A is 12 square inches. The length of Face B is 3 inches and the width is 2 inches, so the area of Face B is 6 square inches. The length of Face C is 2 inches and the width is 1 inch, so the area of Face C is 2 square inches.

Surface Area of a Rectangular Box

A rectangular box is a three-dimensional object with six faces. The surface area of a rectangular box is the sum of the areas of its six faces.

To find the surface area of a rectangular box, we need to know the length (l), width (w), and height (h) of the box. The formula for the surface area of a rectangular box is:

Surface Area = 2(lw + wh + hl)

For example, let’s say we have a rectangular box that is 10 inches long, 6 inches wide, and 2 inches tall.

How To Calculate Surface Area Examples

In mathematics, surface area is the sum of the areas of the faces of a solid object. Surface area is a two-dimensional property, meaning that it is measured in units of length squared. The most common unit of surface area is the square meter.

There are many different ways to calculate the surface area of an object. The most common method is to use a formula specific to the shape of the object. For example, the formula for calculating the surface area of a sphere is 4πr2, where r is the radius of the sphere.

Another way to calculate surface area is to divide the object into small pieces and then calculate the total area of all the pieces. This method can be used for any shape and is often easier than using a formula.

To get started, let’s look at some examples of how to calculate surface area.
