it's 2 dimensional
There are three plane figures and cube, which is three dimensional.
An octagon is two dimensional and has eight sides.
Two-dimensional.
An octagon is a two-dimensional figure. It has no faces but does have 8 sides.
An octagon is a two-dimensional polygon with eight sides which can be regular or irregular
First of all, you did not provide measurements for the octagon. Second, surface area is meant for three-dimensional figures. Octagons are two-dimensional.
An octagon is a two-dimensional shape.
The shape is an octagon.
Adding to what Kittenono said, an octagon is a two dimensional shape which only has length and width. A polyhedron is 3 dimensional which has length, width and height.
Because it is an 8 sided two dimensional shape
A two-dimension shape with eight sides is an octagon. A three-dimensional object with eight sides is an octahedron.
There are three plane figures and cube, which is three dimensional.
An octagon is 2-dimensional, an octahedron is 3-dimensional.
An octagon is an eight-sided two-dimensional object. If each of the eight sides to an octagon were concave, it would still be an octagon. So, yes, it could.
Octagonal An octagon has eight sides and eight angles, and is a two-dimensional shape. In an equilateral octagon, each side has a degree measure of 135.
two-dimensionalOn a+ the answer is three-dimensional
It is an octagon
