Not necessarily. a cube of 1x1x1 of solid gold weights over 19 times than a 1x1x1 cube of water. It takes 2 of the factors, volume, weight, and density to determine the third.
by size,volume and gravity
Its mass.By weight, the amount of matter an object contains is its mass.By size, the amount of matter an object contains is its volume.
You can not measure the volume of a liquid with a measurement designed to determine length. A centiliter is a measurement of volume, or the amount of space that a liquid can consume inside an object. A centimeter, would be a measurement of length and a centigram is a measurement of mass (weight).

By size I think you mean the volume. And no, you also need the density of the object. Which tells you how much a given size weighs.
The volume is the size of an object, length, width and height.
Area is the measurement of the two-dimensional size of an object, and volume is the measurement of the size of an object in three dimensions.
The mass of an object doesn't always depend on its size. It can depend on both size and density. Density is the mass per unit volume of an object, meaning it is how much one unit of an object's volume weighs. What determines that weight is how close together the atoms of that substance is. For example: a metal cube has a higher density than the cork of a bottle; even though they are the same size, their weight is different.
The mass of an object is equal to the object's density multiplied by the volume (size) mass (kg) = density (kg/m3) x volume (m3)
The mass of an object is equal to the object's density multiplied by the volume (size) mass (kg) = density (kg/m3) x volume (m3)
Mass and weight are easy. Use a balance. The two measurements are technically different from each other (weight is dependent on gravity and measures the force that an object exerts on whatever it is sitting on---mass is independent of gravity), but your average balance will give you either. grams or kg are mass, and pounds or ounces are weight. On Earth (given its gravitational constant), the conversion between the two is around 2.2 lb per kg. For volume, it depends on the object. If it is something simple like a cube or a sphere, you can bust out a ruler, make measurements of length, and calculate it based on the dimensions. If it is an irregularly shaped object, the easiest way to do it is to use water displacement. Put water into a device like a graduated cylinder or a beaker that measures volume. Measure the initial volume, add the object, measure the new volume, and subtract. The difference is the volume of your object.
