Solution
\[\text { Lenght of the wooden cuboid = 10 cm }\]
\[\text { Breadth = 8 cm }\]
\[\text { Its volume = 4000 } {cm}^3 \]
\[\text { Suppose that the height of the cuboid is h cm}. \]
\[\text { Then, volume of the cuboid = length } \times \text { breadth }\times\text { height }\]
\[ \Rightarrow 4000 = 10 \times 8 \times h \]
\[ \Rightarrow 4000 = 80 \times h \]
\[ \Rightarrow h = \frac{4000}{80} = 50 cm\]
