How do you find the surface area of the rectangular prism?

To find the surface area of a rectangular prism, you need to follow the formula:
Surface Area = 2lw + 2lh + 2wh
Here's the step-by-step process:
1. Identify the dimensions: A rectangular prism has three dimensions - length (l), height (h), and width (w). Make sure you have these measurements.
2. Calculate the areas of each face: The surface area of a rectangular prism is the sum of the areas of all of its six faces. Each face is a rectangle, so the area can be calculated by multiplying the length by the width.
- The first face has dimensions l x w.
- The second face has dimensions l x h.
- The third face has dimensions w x h.
3. Add up the areas: Multiply each face's dimensions and add them together. This will give you the total surface area of the rectangular prism.
Remember, the formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh. By plugging in the values for length, width, and height, you can find the surface area.
