उत्तर
\[\text { Let h cm be the height of the cuboidal vessel } . \]
\[\text { Given }: \]
\[\text { Length = 10 cm }\]
\[\text { Breadth = 5 cm }\]
\[\text { Volume of the vessel = 300 } {cm}^3 \]
\[\text { Now, volume of a cuboid = length } \times \text { breadth
}\times \text { height }\]
\[ \Rightarrow 300 = 10 \times 5 \times h\]
\[ \Rightarrow 300 = 50 \times h\]
\[ \therefore h = \frac{300}{50} = 6 cm\]
