If you mean the volume of a cylinder then it is:- Volume = pi*32*15 = 424.115 cubic cm to 3 decimal places

Total SA = 245.04 cm2

Volume = (length) x (width) x (height)A cube has all 3 dimensions equal.Volume = (3cm) x (3cm) x (3cm) = 27 cm3

Area of circle of radius 3cm is 3 x 3 x pi ie 9pi sqcm, approx 28.26cm2

All you need to do is times width by length by height 2x5x3 = 30cm^3

The volume of a cylinder is V=PI*r2*h The radius of the cylinder is 3 cm and the height would be 1cm So V = PI*(3cm)2*(1cm) V is approx. 28.3 cm3

I would say that the liquid rises by 1.77cm... This can be obtained as follows given that cylinder of radius(r)=2cm, height(h)=4cm is submerged in another cylinder, determining the volume of the cylinder being submerged =16*pi. When this cylinder is placed in another cylinder the liquid will rise by an amount which equals the volume of the cylinder being inserted.(By Archimedes principle). Using this 16*pi, determine the height using radius= 3cm , we get h=1.77cm
