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
(a) 1800
(b) 2000
(c) 4000
(d) 8000

Solution:

The Volume of the Godown is = 40 × 25 × 10 = 10,000 m³

The volume of one cuboidal box is = 2 × 1.25 × 1 = 2.5 m³

Hence the number of boxes in the room = Volume of the Godown/Volume of one cuboidal Box

Number of Boxes in the Godown = 10,000/2.5 = 4000

Answer is ( c )

✦ Try This: The dimensions of a godown are 50 m, 45 m and 4 m. If it is filled with cuboidal boxes each of dimensions 3 m × 1.5 m × 2 m, then the number of boxes will be (a) 1000 (b) 1500 (c) 2500 (d) 2000

The Volume of the Godown is = 50 × 45 × 4 = 9000 m³

The volume of one cuboidal box is = 3 × 1.5 × 2= 9 m³

Hence the number of boxes in the room = Volume of the Godown/Volume of one cuboidal Box

Number of Boxes in the Godown = 9000/9 = 1000

Answer is (a)
