The surface area of a rectangular box can be calculated by finding the area of each side and adding them together.
The box has 6 sides: 2 sides that are 10cm by 4cm (10cm * 4cm = 40cm²) = 2 * 40cm² = 80cm²
2 sides that are 10cm by 17cm (10cm * 17cm = 170cm²) = 2 * 170cm² = 340cm²
2 sides that are 4cm by 17cm (4cm * 17cm = 68cm²) = 2 * 68cm² = 136cm²
Total surface area = 80cm² + 340cm² + 136cm² = 556cm²
Therefore, Jerry will need 556 cm² of wrapping paper to wrap the present.
