The box measures 10 cm wide , 4cm high ,17 cm long . How much wrapping paper will Jerry need to wrap the present ?
To calculate the amount of wrapping paper needed, you need to find the surface area of the box.
Surface area = 2(length x width) + 2(height x width) + 2(length x height)
Plugging in the dimensions:
Surface area = 2(17 x 10) + 2(4 x 10) + 2(17 x 4)
Surface area = 2(170) + 2(40) + 2(68)
Surface area = 340 + 80 + 136
Surface area = 556 cm²
Therefore, Jerry will need 556 cm² of wrapping paper to wrap the present.
