Aquarium

Try to estimate the weight of the water in an aquarium 50cm long 30cm wide, when poured to a height of 25cm. Calculates the weight of the aquarium's water.

Correct result:

m =  37.5 kg

Solution:

a=50 cm b=30 cm c=25 cm  V=a b c=50 30 25=37500 cm3 V1=V l=V/1000  l=37500/1000  l=37.5 l  ρ=1 kg/l  m=ρ V1=1 37.5=752=752 kg=37.5 kg
