    Cube
In summary, the conversation discusses the naming of a parallelepiped that is not a cube or rectangle, and the difficulty in describing an oblique or tilted parallelepiped without including those shapes. The suggestion of using "non-rectangular" as an adjective to describe the shape is also mentioned, similar to how the set of real numbers can be described without integers.

I was curious what you would call a parallelepiped that isn't a cube and isn't a rectangle and isn't just a rhombohedron? Here is my problem...I need to describe an oblique/tilted parallelepiped but if I just say 'parallelepiped' that would include a cube or rectangle (which I am not referring to). Should I just say oblique parallelepiped? Thank you!

I think parallelepipeds are a subset of Prisms. I need a subset of a parallelepiped. But thank you.

Here's some more definitions to consider:

It looks like though you'll have to use some adjective in front of parallelepiped to describe what you mean like perhaps a non-rectangular parallelepiped which excludes square and rectangular faces.

You quest is similar to describing the set of real numbers without integers. There may be no proper term for it as there is no obvious need to define it.
 

FAQ: What do you call a parallelepiped that isn't a cube?

What is a parallelepiped?

A parallelepiped is a three-dimensional shape with six quadrilateral faces, each of which are parallel to their opposite face. It is a type of prism and can be thought of as a stretched or elongated cube.

How is a parallelepiped different from a cube?

A parallelepiped is different from a cube in its shape and dimensions. While a cube has six square faces of equal size, a parallelepiped has six quadrilateral faces of varying sizes. Additionally, a cube has all angles of 90 degrees, while a parallelepiped has angles of varying degrees.

What is the formula for finding the volume of a parallelepiped?

The formula for finding the volume of a parallelepiped is V = l x w x h, where l is the length, w is the width, and h is the height of the parallelepiped. This formula is similar to the formula for finding the volume of a rectangular prism.

Can a parallelepiped be called a rectangular prism?

Yes, a parallelepiped can also be called a rectangular prism. This is because both shapes have six faces, with each pair of opposite faces being identical and parallel to each other. However, a rectangular prism specifically refers to a parallelepiped with rectangular faces.

What do you call a parallelepiped that isn't a cube?

A parallelepiped that isn't a cube can be called by its specific type, such as a rectangular parallelepiped, a rhombohedral parallelepiped, or a hexagonal parallelepiped. It can also be referred to as a "non-cube" parallelepiped or simply as a parallelepiped.
