A rule of wrapping paper measures 25 inches times 405 inches. The box says being wrapped are 16“ x 14“ x 8“. How many complete boxes can be wrapped with one roll of wrapping paper.

The area of the wrapping paper roll is 25 inches x 405 inches = <<25*405=10125>>10,125 square inches.

The area needed to wrap one box is 16 inches x 14 inches x 8 inches = <<16*14*8=1792>>1,792 square inches.
Therefore, the number of complete boxes that can be wrapped with one roll of wrapping paper is 10,125 square inches / 1,792 square inches = <<10125/1792=5.65>>5.65.
Since you cannot have a fractional number of boxes, you can wrap a total of 5 complete boxes using one roll of wrapping paper.
