उत्तर
\[\text { In the given cuboid, we have }:\]
\[\text { length=1.2 m }\]
\[=1.2\times100 cm (1 m = 100 cm) \]
\[=120 cm\]
\[\text { breadth=30 cm }\]
\[\text { height=15 cm }\]
\[ \therefore \text { Volume of the cuboid = length }\times \text { breadth }\times \text { height }\]
\[=120\times30\times15\]
\[ {=54000 cm}^3 \]
