Best Answer

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.

That is not true: for a pyramid, for example.

The perimeter.

that distance is called the perimeter of the figure.

cube

The perimeter of a polygon is the distance around the outside of the polygon. A polygon is 2-dimensional; however, perimeter is 1-dimensional and is measured in linear units.To find the perimeter of a polygon, take the sum of the length of each side.

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

If the figure is 2-dimensional, it is called the perimeter.

What I think is that the perimeter is the distance around a figure. :)

The distance around a 2 dimensional closed figure is its perimeter.

The perimeter.

No, you must add, not multiply.

that distance is called the perimeter of the figure.

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

Well it matters if you put it in a 3-dimensional or a 2-dimensional figure because if you turn it into a 3-dimensional figure the the surface would have a flat surface with volume and area.If you draw a quad in 2-D then the figure you draw is the surface.

To find the perimeter of two-dimensional shapes, add the lengths of all the sides together. The sum is the perimeter of the figure.

A plane figure.
