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.
2d is 2 dimensional so there is only length and width... edges are only in 3d and 2d figures only have one side...
Its a sphere.

The flat side of a three dimensional solid is called the face. The total area of all of the faces is called the surface area.

The side of a pedon is called a "pedal surface." This is the surface that faces the observer when looking at a soil profile.
It is the total surface area of the 3-D object.
A three-dimensional square is called a cube. To find the surface area of a cube, use the formula: 6 x (side length)^2.
A sphere is a three-dimensional shape with one surface. Or: An irregular blob, an ellipsoid, a torus, plus other shapes. The most interesting 3D object with only one side is of course the Moebus strip.
The Moon's surface that faces Earth is called the near side. This side of the Moon is what we see from Earth and is the side that is always facing towards us due to its synchronous rotation with Earth.
A rectangle cannot have a volume. Only 3-dimensional objects (solids) can have volumes. A rectangle is a 2-dimensional object - or a plane figure.
False.To find the surface area of a three-dimensional figure, find the area of the faces and add them together.
2d is 2 dimensional so there is only length and width... edges are only in 3d and 2d figures only have one side...
