Answer:
900 Boxes can be kept inside the big box.
Step-by-step explanation:
Number of boxes can be kept inside big box :
[tex]= \frac{Volume of big Cuboid}{Volume of small cuboid}[/tex]
Dimensions of big cuboid:
[tex]Length= 9 m\\Width= 4m\\Height= 3m[/tex]
Volume of Big cuboid=
[tex]=Length* width* height\\ =9*4*3\\ =108 m^3[/tex]
Dimension of the small cuboid:
[tex]Length= 40 cm\\ Width= 30 cm\\ Height= 10 cm[/tex]
Volume of the small box:
[tex]=Length*Width*Height\\ = 40*30*10\\ =12000 cm^3 \\or\\= 0.12 m^3[/tex]
Number of small boxes cab be kept in Big Box:
[tex]=\frac{108}{0.12} \\\\=900 Boxes[/tex]
