A trapezium prism has 6 faces
A nonagonal prism has eleven faces.
There is no such word as pectangular. A rectangular prism has six faces.
A cube has six faces and a triangular prism has five faces.
A quadrangular is an adjective, not a noun. A quadrangular pyramid will have a different number of faces from a quadrangular prism, for example.
Six faces.
There can be a quadrangular pyramid or a quadrangular prism or other quadrangular shapes. "Quadrangular" is an adjective, not a noun. You need to be more specific.
Any such figure has only one base; the one that it stands upon. If you are asking "How many faces does the quadrangular prism have?" then its "ends" are both quadrangular shapes (i.e. rectangles) and there are 4 more rectangles forming the "length" of the prism so the answer is 6 These rectangular shapes are more accurately called "faces"; the edges of the rectangles are called "edges", and the corners are called "vertices". Your quadrangular prism has 6 faces, 12 edges and 8 vertices.
A quadrangular prism is a "box". There are 6 faces, 8 vertices and 12 edges. BTW, this satisfies Euler's Formula of F + V = E + 2.
3 faces
