Any kind of prism...:)
Shapes have sides. Do you mean, what shape has 6 sides or, what solid has 6 faces?
Since a cube has 6 faces, you would be looking for a solid shape with only 2 faces and no such solid exists.
Shape
A solid shape with 6 faces, yes. A plane shape with 6 sides is a hexagon.
triangular pyramid
The solid shape that has six rectangles is called a rectangular prism, or a cuboid. This three-dimensional shape has six faces, each of which is a rectangle, and its opposite faces are congruent. Rectangular prisms can vary in dimensions but always maintain right angles between adjacent faces.
A solid shape that has 6 faces and 12 edges is a rectangular prism, also known as a cuboid. Each of its faces is a rectangle, and it has a total of 8 vertices. The 12 edges are formed by the intersections of the faces. Other shapes, like the cube, also fit this description but are a specific case of the rectangular prism.
The solid shape with 6 rectangular faces where not all sides are identical is called a rectangular prism, also known as a cuboid. It has opposite faces that are equal in size, but the lengths of the edges can vary, resulting in different dimensions for each face. This shape is commonly found in everyday objects, such as boxes and bricks.
There is no regular solid with 13 faces.
tetrahedron
Depends. What shape is it?
a sphere
