To find the surface area of a rectangular prism, you need to follow a simple formula. The surface area of a rectangular prism is the sum of the areas of all six faces. Here is how you can calculate it:

  1. Identify the dimensions of the rectangular prism:

    • Length (l)
    • Width (w)
    • Height (h)
  2. Calculate the area of each face:

    • Top and bottom faces: Area = Length * Width
    • Front and back faces: Area = Length * Height
    • Side faces: Area = Width * Height
  3. Add up the areas of all six faces:

    • Surface Area = 2 * (Area of top + Area of bottom) + 2 * (Area of front + Area of back) + 2 * (Area of side)

It’s important to remember that when you measure the dimensions of the rectangular prism, they should be in the same unit (e.g., centimeters, inches, etc.). By plugging in the values for length, width, and height into the formula, you can find the total surface area of the rectangular prism.
