Jerry wants to wrap a present in a box for his mother. The box measures 10cm wide, 4cm high, and 17cm long. How much paper will he need to wrap the present?
First, calculate the total surface area of the box:
- Two sides of the box measure 10cm * 4cm = 40 square cm each.
- Two other sides measure 17cm * 4cm = 68 square cm each.
- Two remaining sides measure 17cm * 10cm = 170 square cm each.
Now, add all the sides together to get the total surface area:
40cm2 + 40cm2 + 68cm2 + 68cm2 + 170cm2 + 170cm2 = 556 square cm
Therefore, Jerry will need 556 square cm of paper to wrap the present.
