Gerry wants to wrap a present in a box for his mother. The box measures 10 cm wide 4 cm high and 17 cm long. How much wrapping paper will Gerry need to wrap a present?

Answer 1

To calculate the amount of wrapping paper Gerry will need, we need to find the surface area of the box.

The box has 6 sides:
- 2 sides that measure 10cm x 4cm = 80 square cm each.
- 2 sides that measure 4cm x 17cm = 68 square cm each.
- 2 sides that measure 10cm x 17cm = 170 square cm each.

So, the total surface area of the box is:
2(80) + 2(68) + 2(170) = 160 + 136 + 340 = 636 square cm

Therefore, Gerry will need 636 square cm of wrapping paper to wrap the present.
