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

Parveen wanted to make a temporary shelter for her car, by making a box-like structure with tarpaulin that covers all the four sides and the top of the car (with the front face as a flap which can be rolled up). Assuming that the stitching margins are very small, and therefore negligible, how much tarpaulin would be required to make the shelter of height 2.5 m, with base dimensions 4 m × 3 m?
