1. **State the problem:** Find the surface area of a rectangular prism with dimensions 4 cm, 5 cm, and 3 cm. 2. **Formula:** The surface area $SA$ of a rectangular prism with length $l$, width $w$, and height $h$ is given by: $$SA = 2(lw + lh + wh)$$ 3. **Substitute the values:** $$SA = 2(4 \times 5 + 4 \times 3 + 5 \times 3)$$ 4. **Calculate each product:** $$SA = 2(20 + 12 + 15)$$ 5. **Add the terms inside the parentheses:** $$SA = 2(47)$$ 6. **Multiply by 2:** $$SA = 94$$ 7. **Answer:** The surface area of the rectangular prism is $94$ square centimeters.
