Question

12 litres of water are poured into an aquarium of dimensions 50cm length, 30cm breadth, and 40cm height. How high (in cm) will the water rise?
(1 litre = 1000cm3)

Answer 1

12 l = 12000 cm3 = x * 30 * 50 => x = 12000/1500 = 8 cm;

Answer 2

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

$height = \frac{Volume}{length.breadth}$

                  = $\frac{12000}{1500}$

                  = 8 cm

So, when we pour 12 litres of water into the aquarium, the water height would be 8 cm
