Question

The rectangular top of a small box has dimensions of 140 mm by 230 mm.

How long (in centimeters) would a ribbon need to be to go all the way around the edge of the top of the box?



740 cm
37 cm
74 cm
7,400 cm

Answer 1

740 cm

Answer 2

This will be 2L + 2W. Hence, it is 2(140) + 2(230)= 280+460=740mm. Next, convert this into cm. Remember that 1cm = 10 mm. So to convert mm to cm, you divide by 10. 740/10 = 74 cm.
