# What is a 3D rectangular object called?

A:
### Quick Answer

**A three-dimensional rectangular object is called a "cuboid," which means "similar to a cube" or "resembling a cube."** It is also referred to as a "rectangular parallelepiped."

A cuboid contains six plane surfaces, with all of its vertices forming 90-degree angles. Two of a cuboid's properties are volume and surface area. The formula for calculating the volume is V = lwh, where "V" denotes the volume, "l" indicates the length, "w" represents the width and "h" is the cuboid's height. The formula for the surface area is A = 2wl + 2lh + 2hw, where "A" is the surface area. A cuboid can be classified as a "prism" because it has a uniform cross-section along its length.

Q:
## How many vertices does a cube have?

A:

Full Answer >**A cube has a total of eight vertices, despite having six square faces that would all have four vertices of their own if pulled apart.**A cube has six square faces that are joined not only at the sides, but at the vertices, essentially resulting in two squares that are joined by four lines, one at each corner.Filed Under: -
