Aquarium

I have an aquarium that is 100 cm long and 40 cm wide and 40 cm in height. We fill it with water. How much will it weigh?

Correct answer:

m =  160 kg

Step-by-step explanation:

a=100 cm dm=100/10  dm=10 dm b=40 cm dm=40/10  dm=4 dm c=40 cm dm=40/10  dm=4 dm  V=a b c=10 4 4=160 dm3  h=1 kg/dm3  m=h V=1 160=160 kg
