उत्तर
\[\text { Length of the tank = 8 m } \]
Breadth = 6 m
Height = 2 m
\[ \therefore\text { Its volume = length } \times \text { breadth } \times \text { height }= (8 \times 6 \times 2) m^3 = 96 m^3 \]
\[\text { We know that 1 } m^3 = 1000 L\]
\[\text { Now, 96 }m^3 = 96 \times 1000 L = 96000 L\]
\[ \therefore\text {P The tank can store 96000 L of water } .\]
