Answer:
3. 2kg/m 4. 1.524 meters
Step-by-step explanation:
3. 20g/cm to kg/m.
(20g÷1000g)kg ÷ (1cm÷100cm)m
1/50kg ÷ 1/100m
1/50 x 100/1=2kg/m
4. 1nch=2.54cm.
1foot=12inches
5feet= 5x12
=60inches
1inch=2.54cm
60nches=60×2.54
=152.4cm
100cm=1m
152.4cm=152.4÷100
=1.524m
thus 5 feet=1.524meers
That is to take the number rounded to the nearest value to two numbers to the right of the decimal:
5.62
