Final answer:
The correct formula for surface area is SA = 2lw + 2lh + 2wh, which is used to calculate the surface area of a three-dimensional rectangular prism.
Step-by-step explanation:
The student's question asks how to calculate the surface area of a geometric shape using the provided formula. The correct formula for surface area is SA = 2lw + 2lh + 2wh, which pertains to three-dimensional shapes such as rectangular prisms, where l stands for length, w for width, and h for height. To properly calculate the surface area, one must multiply the length by the width and by the height in the different configurations specified by the formula and add those products together.
