* * * * *
Or a triangular dipyramid which is two regular tetrahedra (equilateral triangular pyramids) stuck together face-to-face.
cube
A right square based pyramid.
A hexagon is a 2d shape with six sides, a hexahedron is a 3d shape with six faces.
A two dimensional figure with 6 sides is a hexagon. 3d=>hexahedron
A triangular dipyramid.
cube
A tetrahedron has four equilateral triangles as sides
A right square based pyramid.
A cube satisfies that description.
A hexagon is a 2d shape with six sides, a hexahedron is a 3d shape with six faces.
a cube or a dodecahedron * * * * * Not a cube, which has only six sides!
A two dimensional figure with 6 sides is a hexagon. 3d=>hexahedron
A triangular dipyramid.
A 3d shape can have infinite sides
The two congruent 3D triangles were equal in shape, size, length and volume.
It is a cylinder
Rectagular prism, but if it has all congruent sides its a cube
