Given: cuboidal granary with dimensions (8 m × 6 m × 3 m)

Volume of the bag : 0.64 m³

Volume of a Cuboid is given by: l × b × h (here l, b, h are length, breadth, height of the Cuboid respectively)

Let ‘V’ be the Volume of the Cuboidal granary.

∴ V = l × b × h = 8 × 6 × 3 = 144

Let ‘n’ be the number of bags that can fit in cuboidal granary.

∴ n × 0.64 = 144

⇒ n = = 225

∴ n = 225

That is a total of 225 bags, each of volume 0.64 m³ can fit in Cuboidal granary.
