Question:

mandy is wrapping a box 1 ft on each side. the wrapping paper is 26 in by 60 in. what size piece should she cut


Answer:

The wrapping paper must cover a cube with measures 1 ft on each edge.


Surface area of cube = 1 ft * 1 ft * 6 faces of cube = 6 ft²

Surface area of cube = 12 in * 12 in * 6 faces of cube = 864 in²

The wrapping paper must cover 864 in²

There are many ways the paper can be cut.

One way is to cut a piece of wrapping paper 18 inches by 48 inches to begin with (1 ½ feet by 4 feet).

This piece will cover the entire outside area of the cube, but you will need to cut it into smaller pieces to make it fit.



Thanks for writing.
