do a bit of research from the internet, gather lots of information, make a notebook and u can even try making charts

okay, so some of these people are talkin of stuff that i don't even understand, and I'm in 10th grade. So, I would say use models, like go to wal*mart and get styrofoam shapes. then show the surface area compared to the volumes. to find the diameter/radius for circle, when it says 9 in. circle, that means the diameter is 9in. so just divide that by 2, and u get the radius.
you could also make charts, and graphs, but using physical objects just seems more fun.

Take or make a perfect right circular cone/cylinder, cuboid, cube or sphere. Measure the dimensions necessary like height, radius, length etc. Then write neatly the formula of the Surface Area (In case of cone, cylinder and cuboid, both Lateral and Total) and Volume of whichever solid you are taking and calculate them using the measurements you took on a chart paper (full size preferred).

try something unique for example to show that the volume of a cylinder is three times the volume of cone, take a conical vessel and fill it with a liquid (potassium permanganate solution preferred due to deep purple colour or ink water) then take a cylindrical vessel of the same radius and then pour 3 filled volumes of the cone in the cylinder and the cylinder will get filled upto the brim to prove your theory correct. preferably use glass vessels for good presntation.(cheap quality glass vessels would suit you best for a one -time purpose available for about Rs.300-400 in the market)
don't forget to make a neat project file as it always helps you getting marks and impressing the judges.

On your home page type surface areas and volumed of solids on the web search toolbar. click the search botton.
Several sites will appear.

Three different size cubes so you can have different surface areas and volumes. And then what she^^^ said to add on to it.

you should make on volume of cone and relation with cylinder
1/3pie r square h=pie r square h
