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.
true
False
It is the area of the exposed surface. So if you take a cube, the surface area is the sum of the areas of each of the 6 faces. They are all the same in the case of a cube. In general, add up the surface area of each exposed surface and this is the total surface area.
The sum of the areas of each face of the solid.

TRUE: To find the surface area of a three dimensional figure, you must find the area of each of its faces and then add them together.
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.
... face and add them together.
First, find the area of each 2-D face of the figure, then add those up.
False.To find the surface area of a three-dimensional figure, find the area of the faces and add them together.
You find the surface area of each individual face - whether plane or curved - and then sum all those areas together.
Area is the number of square unit needed to cover a surface. Perimeter of a figure is the distance around the figure Perimeter is measurements of each sides added.
No, you must add, not multiply.
It is one of ten faces which, together, make up the 3-D figure called a decahedron. The face is a polygon with 3 to 9 sides.
For many figures, there are known formulae - you can use one of those. Otherwise, if it has flat faces, you can calculate the area of each of its faces, and add them all up. Otherwise, if it is curved (e.g., a sphere), you can divide the surface up into lots of small pieces, of which each will be approximately flat, and add them up. This is (basically) the process called "integration".
