You use units of area, such as square meters, square millimeters, square kilometers, etc.
Area.
Area is of a flat surface whereas volume is of a three dimensional shape.
Area is a 2 dimensional quantity, finding it for something in three dimensions does not make sense. If you want to find an area-like quantity for 3 dimensional shapes, look into surface area, which is the area of each surface of the not flat shape.
well finding the surface area of one face is just like finding the area of a flat rectangle, so all you have to do is find the area of each face and add them up into one sum. i believe that the formula is 2ab + 2bc + 2ac
a flat surface and a ruler
A plane horizontal surface with no depth refers to a flat area on a curved surface.
you find the surface area of a circle by first finding the area of the circles/ two ends. you do this by multiplying the diameter by pi then multiply by two, that is both ends put together then you find the area of the flat part by finding out the circumference of the circle ends, then multiply that by the height of the cylinder. circumference= pi times the diameter then add all your calculation together, and you have the surface area of your cylinder :)
It is called the surface area.
A flat round object is a circle. Surface area of a circle = pi*radius squared.
plateau
Are determined by (a) the shape of the flat surface, (b) the area of the flat surface, and (c) the size of the square units.
The area of the object.
