Unless you have an extremely small house or an extremely large pencil a house has a greater volume than a pencil.
For finding accurate volume of a pencil use a vernier calliper, which measures diameter up to two significant figures. For finding volume of a pencil you will need radius (r) and length (L) of the pencil. V = 3.14 r²L

You cannot. If you know the volume, temperature and pressure of a pencil, you will be no closer to knowing its mass!
We will have to take a lot of approximations to determine this value.In my case, I am taking an unsharped Apsara Platinum Extra Dark Pencil. The length is coming out to be 17.7 cm. Diameter is 0.6 cm. (I am assuming the pencil to be a cylinder).Now applying the formula for volume of a cylinder (pencil)= pi x r^2 x hwhere pi = 3.14r = d/2 = 0.3 cmh = length = 17.7 cm.Volume = 5.00202 ~= 5 cm^2Hence the volume is 5 cm^2 which is equal to 5 ml or 5 cc.
The volume of a pencil case is about 1 millimeter cubed.

Synthetic diamonds can be manufactured at a pressure of 600,000atm. If we took 2 L of gas at 1 atm, and compressed it with a pressure of 600,000 atm, what would the volume of the gas be?

Millimeters
A ruler - plus a pad & pencil to multiply with.

Well, if the measuring jug is large enough, all you need to do is fill it with water high enough that you can completely submerge yourself. Measure the water level before and after you get in, using the marking pencil. The distance between the two marks is your volume.
