form
A 3 dimensional figure
A pyramid
When two sides (called faces) of a 3-dimensional shape meet, they meet at an edge.
This question is faulty. Only 2-dimensional shapes can have their sides counted. For a 3-dimensional shape, you must count either edges or faces.
The net of a 2 dimensional shape can be folded into a 3 dimensional shape
'Object' Do you mean 'shape' or 'solid'. a 2-dimensional shape is an hexagon a 3-dimensional solid is a hexahedron.
vessel
the 3 dimensional shape is a octagon, because their are 8 sides.
A cube is a 3 dimensional shape
you call a two dimensional shape with six sides a hexagon
Triacontatetragon. Most mathematicians would call it a "34-gon."
Not necessarily, if the 3 dimensional shape is a solid like a chunk of rock (with no cavity or hollow portion) it cannot contain liquid. There needs to be a cavity in the 3 dimensional shape.
