उत्तर
Volume of cuboid, V1 =\[l \times b \times h\] = \[9 m \times 8 m \times 2 m = 144 m^3\]
Volume of cube, V2=\[a^3 = 2^3 = 8 m^3\]
Number of cubes formed=\[\frac{Volume of Cuboid}{Volume of cube} = \frac{V_1}{V_2} = \frac{144 m^3}{8 m^3} = 18\]
Thus, 18 cubes can be formed from the given cuboid.
