Answer:-
To find the surface area of a rectangular prism, use this formula: Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height. You calculate the area of all six faces (top, bottom, front, back, left, and right) and add them together. For example, if the prism is 4 cm long, 3 cm wide, and 2 cm high, the surface area would be: 2(4×3 + 4×2 + 3×2) = 2(12 + 8 + 6) = 2×26 = 52 square centimeters. This gives the total area covering the outside of the prism.
