To calculate the amount of wrapping paper needed, you need to find the surface area of the box.

The box has 6 sides, so you need to find the area of each side and then add them up.

Side 1: 10 cm x 4 cm = 40 cm²
Side 2: 10 cm x 4 cm = 40 cm²
Side 3: 10 cm x 17 cm = 170 cm²
Side 4: 10 cm x 17 cm = 170 cm²
Side 5: 4 cm x 17 cm = 68 cm²
Side 6: 4 cm x 17 cm = 68 cm²

Now add up the areas of all 6 sides:
40 cm² + 40 cm² + 170 cm² + 170 cm² + 68 cm² + 68 cm² = 556 cm²

Therefore, Jerry will need 556 cm² of wrapping paper to wrap the present.
