Question

how many 3m cubes can be cut from a cuboid measuring 18m.12m.9m?

Answer 1

no. of smaller cubes = volume of bigger cuboid / vol. of smaller ones
=18×12×9/ 3×3×3
=6×12 =72
ans: 72 cubes

Answer 2

volume of cuboid is 18 x 12 x 9 =1944m³

volume of cube =3³=27 m³

therefore no. of cubes =$\frac{1944}{27}$

=72 cubes ans..
