Solution
\[\text { Lenght of the rectangular diesel tanker = 2 m }\]
Breadth = 2 m
Height = 40 cm
\[ = 40 \times \frac{1}{100}m ( \because 1 m = 100 cm)\]
\[ = 0 . 4 m\]
\[\text { So, volume of the tanker = lenght } \times \text { breadth }\times\text { height }\]
\[ = 2 \times 2 \times 0 . 4\]
\[ = 1 . 6 m^3 \]
\[\text { We konw that 1 } m^3 = 1000 L\]
\[i . e . , 1 . 6 m^3 = 1 . 6 \times 1000 L = 1600 L\]
\[ \therefore \text { The tanker can hold 1600 L of diesel } .\]
