1. **State the problem:** Find the total surface area of a rectangular prism with dimensions 14 in. by 3 in. by 3 in. 2. **Formula:** Surface Area $= 2(lw + lh + wh)$ where $l$, $w$, and $h$ are length, width, and height. 3. **Dimensions:** $l=14$, $w=3$, $h=3$ 4. **Calculate areas:** $lw = 14 \times 3 = 42$ $lh = 14 \times 3 = 42$ $wh = 3 \times 3 = 9$ 5. **Sum areas:** $lw + lh + wh = 42 + 42 + 9 = 93$ 6. **Total surface area:** $2 \times 93 = 186$ 7. **Answer:** Total surface area is **186 in²**.
