उत्तर
Length = 10 m
Breadth = 25 dm
\[ = \frac{25}{10}m ( \because 10 dm = 1m)\]
\[ = 2 . 5 m\]
\[\text { Height } = 25 cm = \frac{25}{100}m = 0 . 25 m\]
\[ \therefore\text { Volume of the cuboid = length } \times \text { breadth } \times\text { height }\]
\[ = 10 \times 2 . 5 \times 0 . 25\]
\[ = 6 . 25 m^3\]
