1) A box is 16m long, 28m broad and 10m high. what is the volume of 100 similar boxes?2) When was S. I unit introduced? (3) 0How many fundamental units are there? What are they? (4) Write down the formulae of area and volume.

1) a=16m

b=28m

c=10m

volume of one box: V=16*28*10=4480m³

volume of 100 boxes: 4480*100=448000m³

2) 1960

3) 7: meter-length, kilogramme-mass, second-time, ampere-electric current, kelvin-temperature, candela-luminous intensity, mole-amount of substance

4) Area: S=a*b

Volume: V=a*b*c
