Question

a 17inh = cm

b 81.28cm= inh

c 5.4 hải lý = km

= m

d 29.7 inh = cm

= m

2 a 15.24 l = \(cm^3\)

= \(dm^3\)

= cc

= ml

3 a 20.2\(mm^2\)= \(m^2\)

= \(dm^2\)

b 15.4 \(dm^2\)= \(m^2\)

= \(mm^2\)

c 0.1\(cm^2\) = \(mm^2\)

= \(m^2\)

d 14\(m^2\) = \(dm^2\)

= \(mm^2\)

e 0.01 \(dm^2\)= \(mm^2\)

= \(m^2\)
