Final answer:
To calculate surface area of a rectangular prism, calculate the area of all the faces (top/bottom, left/right, front/back) and add them together.
Step-by-step explanation:
The subject is about finding the surface area of a rectangular prism. Determining the surface area involves adding up all the areas of the faces of the prism. Given that a rectangular prism has 3 pairs of congruent faces (top and bottom, left and right, front and back). The surface area is calculated as follows:
- Calculate the area of the top and bottom faces by multiplying length by width, then double the result.
- Calculate the area of the left and right faces by multiplying the width by the height, then double the result.
- Calculate the area of the front and back faces by multiplying the length by the height, then double the result.
- Add all the areas together to get the total surface area.
