Freezer

The freezer has the shape of a cuboid with internal dimensions of 12 cm, 10 cm, 30 cm. A layer of ice of 23 mm thick was formed on the inner walls (and on the opening) of the freezer. How many liters of water will drain if we dispose the freezer?

Correct result:

V =  2.3768 l

Solution:

a=1.2 dm b=1.0 dm c=3.0 dm h=2 0.23=0.46 dm  V1=a b c=1.2 1 3=185=3.6 dm3 V2=(ah) (bh) (ch)=(1.20.46) (10.46) (30.46)1.015 dm3 V3=V1V2=3.61.0152.585 dm3 V4=V3 cm3=V3 1000  cm3=2.585 1000  cm3=2585.016 cm3  ρ1=0.9167 g/cm3 m1=ρ1 V4=0.9167 2585.0162369.6842 g m2=m1 kg=m1/1000  kg=2369.6842/1000  kg=2.36968 kg  ρ2=0.997 kg/dm3 V5=m2/ρ2=2.3697/0.9972.3768 dm3  V=V5 l=V5 1  l=2.3768 1  l=2.377 l=2.3768 l
