How Do I Find The Surface Area Of A Rectangular Prim, And Of A Cylinder?
I just missed how to do this because i was sick for 2 days and my teacher won't explain it which i don't get because we're only 7th graders.

The surface area is the sum of all areas of all the shapes which cover the surface of an object.
The Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac
a, b, and c are lengths of 3 sides.
And the Surface Area of Cylinder = 2 pi r 2 + 2 pi r h
where h is the height of cylinder, r is radius of the top
