Aiden needs 5 m of gift-wrap to pack a box. If a roll of gift-wrap has 40 cm of gift paper, how much of gift paper would he fall short of if he uses 12 rolls of wrap? mm

Question

Please answer in mm. Thanks!

Answer 1

12(.4) = 4.8 = 5 - 0.2 meters, 40 cm = 0.4 m

12 rolls of 40 cm each is 0.2 m short of 5 meters.

0.2 m = 20 cm short of 5 meters

= 200 mm short of 5 meters
