What is the formula for calcutlating the area of a rectangular prism?

The area of a rectangular prism, also known as the surface area, can be calculated using the formula: ( SA = 2(lw + lh + wh) ), where ( l ) is the length, ( w ) is the width, and ( h ) is the height of the prism. This formula accounts for the area of all six rectangular faces of the prism. Simply multiply the dimensions as necessary and sum the results before multiplying by two.
