Surface area and volume are in relation to 3D shapes, whereas area is in relation to 2D shapes. Area is used to measure the enclosed space of a 2D shape, volume measures a region in a 3D shape, surface area measures the outer surface of a 3D shape. Both area and surface area are labeled in square units but with volume the label is in cubic units. The geometric shape that I would choose is a sphere to find the volume of sphere I would use the formula 4/3 x pie x radius cubed. Say if a sphere had a radius of 4ft. I would first find the value of 4 cubed which is 64ft. Now to finish the problem and find the volume of the sphere I would multiply 4/3 x pie x 64, which equals 268.08ft cubed. Using that same sphere, to find the surface area, I must use the formula 4 x pie x radius squared. Surface Area = 4 x pie x 16, which has a value of 201.06 sq. ft
