# Aquarium volume

The aquarium has a cuboid shape and dimensions a = 0.3 m, b = 0.85 m, c =? , V = ?. What volume has a body, if after dipping into the aquarium water level rises by 28 mm?

Result

V2 =  7.14 l

#### Solution:

$a=3 \ \text{dm} \ \\ b=8.5 \ \text{dm} \ \\ h=28/100=\dfrac{ 7 }{ 25 }=0.28 \ \text{dm} \ \\ V_{2}=a \cdot \ b \cdot \ h=3 \cdot \ 8.5 \cdot \ 0.28=\dfrac{ 357 }{ 50 }=7.14 \ \text{l}$
