A pentagonal cube is not a standard geometric shape. However, the term might refer to a cube-like structure or a polyhedron that incorporates pentagonal faces in some capacity. Here are some interpretations and related shapes that involve pentagons and cubes:
Pentagonal prism
This shape has two pentagonal faces and five rectangular faces. The pentagons are parallel to each other, and the rectangles connect the corresponding sides of the pentagons. The shape is a 3D figure that extends a pentagon into the third dimension.
Truncated cuboctahedron
It is a complex 3D shape with 12 regular pentagonal faces and 60 regular hexagonal faces. It has a total of 120 faces, 120 vertices, and 60 edges. This shape can be viewed as having a cube and an octahedron, which are truncated in such a way that their vertices are removed, resulting in a new shape with pentagons and hexagons as faces.
Archimedean solids
These are convex solids that have identical vertices and are made up of two or more regular polygons. Some of these solids have pentagonal faces, such as the truncated dodecahedron, snub dodecahedron, and others. However, these shapes are not cubes but rather their own unique 3D configurations.
Platonic solids
These are the most basic types of regular polyhedra that are similar to Archimedean solids. The five shapes are tetrahedron, cube, octahedron, dodecahedron, and icosahedron. The pentagons referred to in the question might be referring to the dodecahedron, which has 12 regular pentagonal faces.
5-cube
This term refers to a higher-dimensional cube, also called a penteract. This shape is a 5D figure that extends a regular cube into the fifth dimension. Just as a regular cube is made up of six square faces in 3D space, a 5-cube is made up of eight 4D hypercube faces in 5D space. This shape cannot be visualized directly, but it can be mathematically conceptualized as a cube-like structure in higher dimensions.
When buying a pentagonal Rubik's cube for sale, business owners should consider the skill level of their target customers. Beginners usually practice solving cubes with simple patterns. At the same time, experienced players go for complex models with challenging patterns. To cater to various skill levels, buyers should get pentagonal cubes in different designs and colors.
Business owners should get pentagonal cubes made of high-quality plastic material. The cubes should also have sturdy construction with smooth edges. This allows them to withstand regular turning without breaking. Also, they should have solid corner-cutting to improve performance during solving.
Buyers should get pentagonal cubes with customizable features. Such models allow users to change the tension and spring settings. This helps to achieve the desired stiffness and flexibility. Also, they should get cubes that use advanced magnetic positioning system. This helps to align the pieces accurately during solving.
Buyers should consider the size and weight of the pentagonal cubes. They should choose models that are comfortable to hold and handle. At the same time, they should avoid heavy cubes as they can cause fatigue during prolonged use. Also, they should get cubes with adjustable size features. This allows users to adjust the size according to their preferences.
To attract a large number of customers, buyers should get pentagonal cubes suitable for both display and competition use. Such models come with additional accessories like display stands, extra springs, and tensioning tools. Additionally, buyers should get cubes suitable for various solving styles. For instance, some cubes are ideal for speed solving while others for one-hand solving.
Buyers should consider the brand reputation when selecting pentagonal cubes. They should research and identify brands that are well-known for their quality and innovative products. Also, they should read reviews to get feedback from other customers about their experience with the brand's products.

Q1: What is a pentagonal cube?
A1: A pentagonal cube is a non-convex polyhedral that comprises a cube with five faces as pentagonal faces.
Q2: How many total faces does a pentagonal cube have?
A2: A pentagonal cube has a total of 10 faces, of which five are pentagons and the other five are squares.
Q3: What is the shape of the pentagonal cube's faces?
A3: The faces of the pentagonal cube are in two shapes: square and pentagonal faces. The pentagonal faces have five angles, while the square faces are all equal and have four right angles.
Q4: What is the dual of the pentagonal cube?
A4: The dual of the pentagonal cube is known as the pentagonal cuboctahedron.
Q5: What is the vertex figure of a pentagonal cube?
A5: The vertex figure of a pentagonal cube is a (5, 4, 1) which means that at each vertex of the cube, there are five faces meeting, four faces around the vertex, and one face is incident to the vertex.
