its still hard when we i find the surface area of a rectanguar prism.
Imagine that you're wrapping a box in gift wrap.

To find the surface area of a rectangular prism, you need to find the area of each of its sides and then add them together. The sides of a rectangular prism are typically referred to as the top, bottom, right, left, front, and back faces.
To find the area of each side:
1. Top face: The top face of a rectangular prism is a rectangle. To find its area, multiply the length of the rectangle by its width.
2. Bottom face: The bottom face is also a rectangle with the same dimensions as the top face. So, to find its area, you multiply the length by the width.
3. Right face: The right face is a vertical rectangle connecting the top and bottom faces. To find its area, multiply the height of the rectangular prism by its width.
4. Left face: The left face is also a vertical rectangle with the same dimensions as the right face. So, its area is equal to the height multiplied by the width.
5. Front face: The front face is a vertical rectangle connecting the top and bottom faces. To find its area, multiply the height of the rectangular prism by its length.
6. Back face: Similar to the front face, the back face is a vertical rectangle with the same dimensions as the front face. Therefore, its area is also equal to the height multiplied by the length.
Once you have found the area of each side, simply add them together to get the total surface area of the rectangular prism.
