Question

A tea packet measures $10cm\times 6cm\times 4cm$. How much such packet can be placed in a cardboard box of dimensions $50cm\times 30cm\times 0.2m$ ?

Answer 1

Measure of a packet = 10cm*6cm*4cm

Volume of a packet=$(10\ast 6\ast 4){cm}^3=240{cm}^3$

Measure of cardboard box = 50cm*30cm*0.2m

Volume of cardboard box = $(50\ast 30\ast 20){cm}^3=30000{cm}^3$

Number of packets = $\frac{Volumeofcardboardbox}{Volumeofapacket}$

$=\frac{30000}{240}=125$

So,there are 125 packets that can be placed in the given cardboard box.
