Density = mass / Volume
You are given the mass of the cyllinder (m = 4 kg).
You are given the dimentions of of the cyllinder which you can then use the find the volume.
The volume of a cyllinder = (pi*r^2)*h
where pi is the constant pi (the ratio of the circumfrance of a circle to its diameter, ~3.1415), r is the radius, and h is the height.
Using this formula, I calculate the volume of the cyllinder to be about 9425 cm^3.
D = m / v
D = 4000 g / 9425 cm^3
D = 4.24 E-1 g/cm^3 or 424 kg/m^3
This is a low density by comparison to many other things, for example, water has a density of about 1 g/cm^3.
Next Time, do your own home work.

Density = Mass/ Volume.
Volume = piR^2 * H
V= pi*10*10*30 cm^3
D= 4Kg/(pi*10*10*30)
You might want to change the units to get it into a more standard form

mass = 4000gm
volume = Pi*r*r*h
=3.14*10*10*30
=9420cm*3
dencity = mass/volume
=4000/9420
=0.425 gm/cm*3

It'll hold a lot of squid. Why not figure out how much?
Do your homework or you'll end up like me, sitting here talking to people like you, extolling the virtues of
