A decagon is the ten-sided polygon (two dimensional shape). A decahedron is a ten-sided thee-dimensional shape. A ten-sided die can also be called a pentagonal trapezohedron.
decagon.
A shape with ten sides is called a decagon.
Assuming a regular ten-sided shape, of which every side is the same length, each side will be 114/10 = 11.4 centimetres.
A decagon is a shape that has ten sides. As long as the figure has ten sides to it, then it is a decagon.

Decagon
That depends on what the shape of the faces of each side of the polyhedron is - since a ten-sided figure does not create a regular polyhedron, it is impossible to calculate its volume based simply on this information.
a face
A decagon. A two-dimensional shape (plane figure, or polygon) which has ten sides is a decagon. A three-dimensional shape (polyhedron) which has ten sides (plane faces) is a decahedron.
A plane figure bounded by some numbers of straight sides is called a polygon. Thus a polygon with ten-sided is called a decagon.
-- Measure or figure out the length of each side. -- Add up all the lengths of all the sides. -- The answer is the perimeter of the shape.
