There is no such thing. A hexagon is a two dimensional figure. A three dimensional figure with six vertices is an octahedron.
i dont no
The answer is in the question it is a 3 dimensional figure such as a pyramid
A two-dimensional shape that can be folded into a three-dimensional figure is often called a net.
It is the cross-section of the figure by the plane.
A face
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?
There is no such thing. A hexagon is a two dimensional figure. A three dimensional figure with six vertices is an octahedron.
a solid figure
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.
i dont no
It is a three dimensional figure of some sort.
It is so by definition.
The answer is in the question it is a 3 dimensional figure such as a pyramid
The answer is surface area.
Because that is how a polyhedron is defined.
