What is a three-dimensional trapezoid called?

A three-dimensional trapezoid is also known as a trapezoidal prism. Three-dimensional figures, also referred to as 3D objects, are figures in space that have length, width and depth.

The three-dimensional figure sides are its flat surfaces. The edges are where the faces meet, and the vertices are the corners or points where three or more surfaces meet. The volume of a three-dimensional object is the amount of cubic space inside the shape, and it is measured in cubic units, such as cubic inches or cubic gallons. Some of the common types of three-dimensional figures are cone, cube, sphere, pyramid and cylinder.
