Its total surface area.

NO. This is the way to get the volume of a prism, not the surface area of any three-dimensional figure. To find the surface area of a three-dimensional figure, you must find the area of each of its faces and then add the side-areas together.

No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.

Area is the measure of a two-dimensional space enclosed by a shape, and surface area is the sum of all the areas of the faces of a three-dimensional solid.

To find the area of the remaining figure, subtract the area of the removed portion from the total area of the original figure.

The term area is generally reserved for a two-dimensional polygon, but surface area is the term of the area of the different surfaces on a three-dimensional figure---the faces on the object. So no, they are not the same.

No, you must add, not multiply.

surface area

You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?

False. You must find the area of each of the faces, then add those together.
