The surface area of the 3-D figure will be the total of the areas of the 2-D figures.
Notice the exponents in these two statements.Those little tiny numbers tell the whole big story:(the ratio of the surface areas of similar figures) = (the ratio of their linear dimensions)2(the ratio of the volumes of similar solids) = (the ratio of their linear dimensions)3
Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*42 => 201.0619298 Surface area of the sphere = 201 square units correct to three significant figures.
SA = 2lw+2lh+2wh
to find the surface area you have to first find the area of each part then add the areas together.

you put: a squared over b squared = surface area of the smaller solid over surface area of the bigger solid
SA = 2lw+2lh+2wh
First find the radius by dividing 19 by 2*pi which is 3.023943919 cm Surface area of a sphere (the ball) = 4*pi*radius2 Surface area = 4*pi*3.0239439192 => 114.9098689 Surface area of the ball: 115 square centimeters correct to three significant figures.

It depends on the surface area of what!
You don't. You can find the area of geometric figures, not of numbers.
The trapezoid is a plane figure which has surface Area, but no volume but if there was a 3d figure your equation would be. The Surface Area of a trapezoid = ½(b1+b2) x h X Height of figure.
The formula to find the surface area of a parallelogram is Base*Height.
