Answer 1

To find the surface area of the box, we need to find the area of each of the six sides of the box and then add them all together.

The box has 3 pairs of sides:
1. The top and bottom: 17 cm x 4 cm = 68 cm^2 (2 times for both sides)
2. The front and back: 17 cm x 10 cm = 170 cm^2 (2 times for both sides)
3. The two sides: 4 cm x 10 cm = 40 cm^2 (2 times for both sides)

Now, we add up all the areas:
68 cm^2 (top and bottom) + 170 cm^2 (front and back) + 40 cm^2 (two sides) = 278 cm^2

Jerry will need 278 cm^2 of wrapping paper to wrap the present in the box.
