The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2. "r" is the radius; if you find the diameter of Earth somewhere, divide it by 2 to get the radius.

Surface area = 4*Pi*radius2
Assuming the moon to be a sphere, the formula to find its surface area is 4/3*pi*r^3 where r is the radius of the moon.
How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
Area = ( length of a side)2
You find the surface area of a cube by using the formula 6e2. In this case, e=edge.
