Question

A cuboidal vessel is 10 cm long and 5 cm wide. How high it must be made to hold 300 cm³ of a liquid?

Answer 1

\[\text { Let h cm be the height of the cuboidal vessel } . \]

\[\text { Given }: \]

\[\text { Length = 10 cm }\]

\[\text { Breadth = 5 cm }\]

\[\text { Volume of the vessel = 300 } {cm}^3 \]

\[\text { Now, volume of a cuboid = length } \times \text { breadth
 }\times \text { height }\]

\[ \Rightarrow 300 = 10 \times 5 \times h\]

\[ \Rightarrow 300 = 50 \times h\]

\[ \therefore h = \frac{300}{50} = 6 cm\]
