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.

Explanation:

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

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
