A water displacement test. You take a graduated cylinder full of water and read how many mL you have. Then you place the object in the graduated cylinder and read how much the water has risen. You subtract your first value from the value with the object in the cylinder. The amount you then come up with is the area in mL. This can be converted to cm cubed since they are equal.
Displacement is the process used to find the volume of an irregular object. This is done by submerging the object in water and measuring either the height the water rises or the volume of water that overflows the container.

method usede to figure the volume of an irregular shaped object
The method used to measure an irregular solid by placing it in water is called dispersion. If you note the level of the water before placing the object in and the level after, you can find the volume of the object by calculating the difference.
Make a mold of the object and then fill the mold with water and measure the volume of the water.
The water displacement method is typically used to find the volume of an irregular solid. The object is submerged in a known amount of water, and the increase in water volume is measured. This increase in volume is equal to the volume of the irregular solid.
Water displacement
It is a method called displacement. Displacement is a method that many scientists use. First you put a certain amount of water in a container (test tube, beaker). Second you Measure how many milliliters of water you put into it. Next you Add your irregular object into the water. Then you measure how many milliliters the water level rose. Then you subtract your second measurement with the irregular shaped object in it by your first measurement without the object in it and it will give you the volume of your irregular shape object.
Drop it into a measurement device such as a graduated cylinder with enough liquid to cover the object. Assuming the object sinks, the increase in mls is the volume of the object (1 ml = 1 cm^3)
Calculus can be used to find the surface area of any object given that you know the equation describing said object. It's usually easier to find the area from experiment or through using a combination of existing models to approximate the surface area
It's called displacement. Say you have a closed irregular object. It takes up space. Dunk it in water and it displaces the water. Finding out how much water was displaced tells you how much space the object took up. That's the volume =P.
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
