A) calculate the height of the aquarium if the water reaches 5 cm below the edge
B) calculate the total volume of the aquarium

Correct answer:

c =  35 cm
V =  70 l

Step-by-step explanation:

a=5 dm cm=5 10  cm=50 cm b=4 dm cm=4 10  cm=40 cm V=60 l cm3=60 1000  cm3=60000 cm3 d=5 cm  V=a b (cd)  c=d+a bV=5+50 4060000=35 cm
V1=a b c=50 40 35=70000 cm3 V=V1 l=V1:1000  l=70000:1000  l=70 l=70 l
