The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object. In geometry, there are different shapes and sizes such as sphere, cube, cuboid, cone, cylinder, etc. Each shape has its surface area as well as volume.

Surface area is a special example of area. It tells us the number of square units it would take to cover the faces of the 3D figure. Volume is a 3 -dimensional measurement. It tells us the number of cubic units it would take to fill a 3D figure. We measure volume in units like cubic centimeters ( cm 3 ), cubic inches, and cubic meters.
Surface area refers to the flat surfaces that surround the solid and is measured in square units. Volume refers to the space inside the solid and is measured in cubic units. Imagine that you have a square flat surface with width and length.
Sep 17, 2020 · Find the area of each face. Add up all areas. SA = 2B + 2πrh S A = 2 B + 2 π r h. Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height. SA = 4πr2 S A = 4 π r 2. Find the area of the great circle and multiply it by 4.
