A three dimensional trapezium is commonly referred to as a trapezoidal prism or a truncated prism. In geometry, a trapezoidal prism is formed by extending a trapezium (a four-sided figure with at least one pair of parallel sides) in a direction perpendicular to its base. This results in a solid shape with two trapezoidal faces and four rectangular lateral faces.
The properties of a trapezoidal prism can be summarized as follows: it has two bases that are parallel trapeziums, while the lateral faces are rectangles that connect the corresponding sides of the trapeziums. This type of solid can be found in various applications, including architecture and design, due to its unique shape and volume.
