It has six faces.
4
It has 0. All of the faces intersect.
Seven. The lateral faces are usually all rectangular.
i think there is 12 faces are in the decagonal prism this is mhel a decagonal prism has 11 faces
A brick has 8 corners.
All of the adjacent faces are perpendicular. So there are 6 faces x 4 faces adjacent to each face So there are 24 perpendicular faces in a rectangular prism.
Assuming a block is a cuboid (or a brick), it has 6 faces, 12 edges and 8 vertices.
a pyramid has for faces and a base so all in all 5 faces the four on the outside are triangular and the base is square :)
None. All faces on a pyramid are flat.
there are 24 right angles in all faces of a cube
It has 0. All of the faces intersect.
Icosahedron are a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles.
yes there are congruent because of the shape * * * * * Wrong. The faces may me congruent but don't have to be. Think of a brick (a rectangular prism). Its top and side are certainly not congruent. And there is no requirement, in such a prism, for the top and bottom to be congruent either.
A cube has 6 faces (all square faces), 8 vertices and 12 edges.
Icosahedron are a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles.
A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.
Seven. The lateral faces are usually all rectangular.
0 for all of them
