Question

A store room in the form of a cuboid has dimensions $42m\times 35m\times 21m.$ How many cuboidal boxes can be stored in it if the volume of each box is $0.7m^3?$

• A. 30870
• B. 44000
• C. 44100
• D. 4200

Answer 1

The correct option is C 44100

Given,
$\text{Volume of box}=0.7m^3$

Dimensions of the store room
$=42m\times 35m\times 21m$

$\text{Volume of store room}=42\times 35\times 21$
$=30870m^3$

Therefore, the number of boxes that can be stored in the room

$=\frac{\text{Volume of the room}}{\text{Volume of one box}}=\frac{30870}{0.7}=44100$

$\therefore$ Number of cuboidal boxes that can be stored in the room is 44100.
