Answer:
Since the tin has a square base,
l=b=12cm, h=17.5cm
Now, capacity (volume) of tin
=l×b×h
=12cm×12cm×17.5cm
=2520cm³
Now, for cylindrical tin
radius=diameter/2
=12cm/2
=6cm
height=17.5cm
Capacity (volume)of cylinder
=πr²h
=(22/7)×(6cm)²×17.5cm
=1980cm³
So, the tin with square base has more capacity by
=2520cm³-1980cm³
=540cm³
