To wrap the present, Jerry will need to cover the surface area of the box. The surface area of a box can be calculated by finding the area of each face and adding them together.
The box has six faces:
- Top: 10 cm x 17 cm = 170 cm²
- Bottom: 10 cm x 17 cm = 170 cm²
- Front and back: 4 cm x 17 cm = 68 cm² each, for a total of 136 cm²
- Left and right sides: 4 cm x 10 cm = 40 cm² each, for a total of 80 cm²
To find the total surface area, we add up all the areas:
170 cm² + 170 cm² + 136 cm² + 80 cm² + 80 cm² + 136 cm² = 772 cm²
Therefore, Jerry will need 772 cm² of wrapping paper to wrap the present.
