To find the capacity of the fish tank in litres, we first calculate the volume in cubic centimeters (cm³) and then convert it to litres.
1. **Calculate the volume in cubic centimeters:**
\[
\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}
\]
Plugging in the values:
\[
\text{Volume} = 40 \, \text{cm} \times 25 \, \text{cm} \times 30 \, \text{cm}
\]
\[
\text{Volume} = 40 \times 25 = 1000 \, \text{cm}^2
\]
\[
\text{Volume} = 1000 \times 30 = 30000 \, \text{cm}^3
\]
2. **Convert cubic centimeters to litres:**
Since 1 litre is equal to 1000 cubic centimeters, we divide the volume in cm³ by 1000:
\[
\text{Volume in litres} = \frac{30000 \, \text{cm}^3}{1000} = 30 \, \text{litres}
\]
Thus, the capacity of the fish tank is **30 litres**.
