उत्तर
The dimensions of a godown are 40 m, 25 m and 10 m. If it is filled with cuboidal boxes each of dimensions 2 m × 1.25 m × 1 m, then the number of boxes will be 4000.
Explanation:
Given, dimensions of a godown are 40 m, 25 m and 10 m.
∴ Volume of godown = 40 × 25 × 10 = 10000 m3
Now, volume of each cuboidal box = 2 × 1.25 × 1 = 2.5 m3
∴ The number of boxes, that can be filled in the godown = `"Volume of godown"/"Volume of each cuboidal box"`
= `10000/2.5`
= 4000
