The size of that area is known as the "area" of the figure.
The area covered by an enclosed figure
You are finding the volume of the solid figure.To find the volume of a solid figure, depending on the size of the object, you can use a graduated cylinder. You can fill the cylinder up to x amount of water and then measure the amount after dropping the solid into the water, and then subtract the amount before, from the amount after, to get the volume of a solid. You can also use simple mathematics to figure the volume of the solid. There are different formulas for calculating volume for different types of solid figures.
