It is not clear whether the question means the shape has ten faces of which 4 are square and 6 are not, or 6 faces of which 4 are square. In the first case the shape would be a 16-hedron. The second is impossible.
A triangular pyramid.
A triangular pyramid, also known as a tetrahedron, has four faces. This three-dimensional geometric shape is made up of four triangular bases.
Pyramid
A tetrahedron, also called a pyramid is a three-dimensional shape with four faces.
tetrahedron
A triangular pyramid. This is one where all the faces are triangles - a three-sided base, from which three triangular faces rise to a single point - the apex.
A tetrahedron is a 3 dimensional shape bounded by 4 triangular faces. It has 4 vertices and six edges. Three faces meet at each vertex so that the shape is self-dual.
