Examples, solutions, videos, and worksheets to help grade 5 learn how to find the surface area of a rectangular prism.

To find the surface area of a rectangular prism, you need to calculate the areas of its six faces and then add them together. The formula for the surface area of a rectangular prism is:

Surface Area (SA) = 2lw + 2lh + 2wh

Where:

- l is the length of the rectangular prism.
- w is the width of the rectangular prism.
- h is the height of the rectangular prism.

Here’s a step-by-step guide to finding the surface area of a rectangular prism:

- Measure the length (l), width (w), and height (h) of the rectangular prism in units.
- Use the formula above to calculate the surface area. Multiply each pair of sides by 2 and add them together.
- Plug the values of length, width, and height into the formula:

SA = 2lw + 2lh + 2wh

Example:

Find the surface area of a rectangular prism with the following dimensions:

Length (l) = 4 units

Width (w) = 3 units

Height (h) = 5 units

Using the formula:

SA = 2lw + 2lh + 2wh

SA = 2(4)(3) + 2(4)(5) + 2(3)(5)

Now calculate each term:

2lw = 2(4)(3) = 24 square units

2lh = 2(4)(5) = 40 square units

2wh = 2(3)(5) = 30 square units

Now, add these areas together:

SA = 24 + 40 + 30

SA = 94 square units

So, the surface area of the rectangular prism is 94 square units.
