How to find surface area for rectangular prisms easy

Answer 1

To find the surface area of a rectangular prism, follow these steps:

1. Identify the length, width, and height of the rectangular prism.

2. Calculate the surface area of each face of the rectangular prism:
- The surface area of the top and bottom faces is equal to the length times the width.
- The surface area of the front and back faces is equal to the length times the height.
- The surface area of the side faces is equal to the width times the height.

3. Add up the surface areas of all the faces to find the total surface area of the rectangular prism.

Here is the formula for finding the surface area of a rectangular prism:
Surface Area = 2lw + 2lh + 2wh

Simply plug in the length, width, and height values into the formula and solve to find the surface area of the rectangular prism.
