Answer:
250 boxes
Step-by-step explanation:
Volume of a cuboid = (length × breadth × height)
Bigger cuboid
Length = 30cm
Breadth = 50cm
Height = 20cm
Volume of bigger cuboid = (30×50×20)
Volume =30 000cm^3
Smaller cuboid
Length = 3cm
Breadth = 10cm
Height = 4cm
Volume of smaller cuboid = (3×10×4)
Volume = 120 cm^3
No of small boxes needed to fill bigger box =
30000/120
= 250 smaller boxes
I hope it helps :)
