Question

the family is taking 3 gift,-, wrapped present (using the same boxes). How much wrapping paper will they need? Draw a net to represent one of the boxes

Answer 1

Determine the surface area of box.

$\begin{gathered} SA=2(\frac{3}{2}\cdot\frac{4}{3}+\frac{3}{2}\cdot2+\frac{4}{3}\cdot2) \\ =2(2+3+\frac{8}{3}) \\ =2(\frac{23}{3}) \\ =\frac{46}{3} \end{gathered}$

So wrapping paper required for one box is 46/3 square feet.

Determine the wraping paper for 3 boxes.

$\frac{46}{3}\cdot3=46$

So 46 square feet of wrapping paper is required for 3 boxes.

Draw a net to represent one box.
