Answer 2

Given:

A fish tank 45 cm by 20 cm by 10 cm is full of water how many litres of water are there in the fish tank​

To find:

How many litres of water are there in the fish tank​?

Solution:

We know,

$\boxed{\bold{Volume \:of\:a\:cuboid = length\times breadth \times height}}$

The dimensions of the fish tank:

Length = 45 cm

Breadth = 20 cm

Height = 10 cm

∴ The volume of the fish tank is,

= Volume of a cuboid

using the formula above

= 45 × 20 × 10

= 9000 cm³

Also, we know,

$\boxed{\bold{1 \:cm^3 = \frac{1}{1000} \:litres }}$

Now,

The volume of water in litres in the fish tank is,

= $9000 \times \frac{1}{1000} \:Litres$

= $\bold{9\:litres }$

Thus, there are 9 litres of water in the fish tank.
