Match each metric unit with the best estimate of its length or distance
1. height of a stove
2. thickness of about 10 sheets of paper
3. distance along a road spanning about 10 telephone☎ poles
4. width of a key on computer keyboard
a. 1 km
b. 1m
c. 1 cm
d. 1 mm

1.       Match the unit of measure in to given situation:
=>  For the height of stove, use meter to measure it
=> To measure the thickness of about 10 sheets of a paper – use mm or millimeter
=> TO measure the distance along a road spanning about 10 telephone poles, use kilometers
=> And to measure the width of a key on a computer – use centimeter
Thus the answer for number 1 is B, for number 2 is d, for number 3 is A and for number 4 is c.

Neither is the answer
