Question

How many alarm clocks of size $5cm\times 10cm\times 10cm$ can be packed into a box of size $1m\times \frac{1}{2}m\times \frac{3}{4}m$?

Answer 1

According to your question,

size of 1 alarm clock $=5cm\times 10cm\times 10cm=500$ cubic cm

size of box $=1m\times \frac{1}{2}m\times \frac{3}{4}m$

we know that ,

$1m=100cm$

so, we can also write

size of box $=100cm\times 50cm\times 75cm=375000$ cubic cm

alarm clock can be packed = size of box / size of 1 alarm clock

$=\frac{375000}{500}$

$=750$

ANSWER : $750$ alarm clock can be packed into the given box.
