Solution
\[\text { In the given cuboid, we have }:\]
\[\text { length=1.5 dm }\]
\[ =1.5\times10 (1 dm = 10 cm) \]
\[ = 15 cm\]
\[\text { breadth=2.5 dm=2.5 }\times10 cm=25 cm\]
\[\text { height=8 cm }\]
\[ \therefore \text { Volume of cuboid = length }\times \text { breadth }\times \text { height }\]
\[=15\times25\times8\]
\[ {=3000 cm}^3\]
