A box has a length of 15 in., a width of 7 in., and a height of 9 in. If Tara plans to cover the box with wrapping paper, how much wrapping paper will she need?

Respuesta :

We have to calculate the area of the box.

area (box)=2(lenght x width) + 2(lenght x height) +2(width x height)

area (box)=2(15 in x 7 in) + 2(15 in x 9 in) + 2(7 in x 9 in)=
=2(105 in²)+2(135 in²)+2(63 in³)=210 in²+270 in²+126 in²=606 in².

Answer: she need 606 in² of wrapping paper.
