The water will rise to 8 cm
Further explanation
Given:
The aquarium dimension = 50 cm x 30 cm x 40 cm
Volume pour to the aquarium = 12 litres = 12000 cm³
First step
We will calculate the volume of the aquarium:
Volume = 50x30x40
= 60000 cm³
When we pour 12000 cm³ water into the aquarium, only the height changed, the length and breadth are the same.
Now, we calculate the height when the volume is 12000 cm³
Volume = length x breadth x height
[tex]height = \frac{Volume}{length.breadth}[/tex]
= [tex]\frac{12000}{1500}[/tex]
= 8 cm
So, when we pour 12 litres of water into the aquarium, the water height would be 8 cm
