The aquarium

The aquarium is 120 cm long, 70 cm wide, and 96 cm high. How high does the water reach if we fill it with 168 liters?

Correct answer:

h =  20 cm

Step-by-step explanation:

a=120 cm dm=120:10  dm=12 dm b=70 cm dm=70:10  dm=7 dm c=96 cm dm=96:10  dm=9.6 dm V=168 l dm3=168 1  dm3=168 dm3  h1=V/(a b)=168/(12 7)=2 dm h=h1 cm=h1 10  cm=2 10  cm=20 cm h<c
