A Prismthe faces are called bases
it has six faces
A cone has two faces.
6 faces
interior i guess
A triangle has 3 sides and 3 vertices. Strictly speaking, the interior of the triangle is not part of the triangle so it has no faces. However, a triangular lamina will have two faces - one from above and one from below.
No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.
No. A rectangle is a two-dimensional shape with four sides and four interior angles measuring 90 degrees. A shape with six square faces would be a cube.
All prisms have a face on each end. Additionally, they will have a number of faces corresponding to the number of sides on the polygon that is on an end. For a triangular prism, that's 2 + 3 = 5 faces. For a square prism, that's 2 + 4 = 6 faces. For your pentagon prism, that's 2 + 5 = 7 faces.
Faces
For a uniform hexagonal prism, there are four pairs of parallel sides. On a hexagonal prism, the six side faces have interior angles of 120 degrees, so each face is parallel with one three over from it. The ends (base and top) are parallel and 90 degrees from each side.
