Question 1

Is surface area the same as area?

Accepted Answer

Not exactly. Surface area is for 3D outer faces and uses square units. Area is a 2D measure.

Question 2

Should I include the top and bottom for cylinders?

Accepted Answer

If you are calculating total surface area, yes. Some tasks use lateral surface area only, which excludes the bases.

Question 3

What about units and square meters?

Accepted Answer

Surface area always uses squared units (m^2, ft^2, etc.). Match unit conversions carefully before input.
