It is a three dimensional figure of some sort.
triangular prism
A regular tetrahedron
Pyramid
A net is a two-dimensional figure which can be folded into a three-dimensional figure. It's a little difficult to describe in words . . . To make a regular triangular prism, start with a rectangle, and divide it into three equal (narrow) rectangular strips. on the two ends of one of these strips, make equilateral triangles.
Since a frustum is a portion of a solid, three-dimensional figure, and a rectangle is a plane, two-dimensional figure, there can be no such thing as the frustum of a rectangle.

A cube is a three dimensional object with all sides of equal length. A rectangle is a two dimensional figure with two pairs of sides equal in length. Three dimensional is like a rubrics cube, something you can hold. A two dimensional figure is something you can not hold, a drawing is two dimensional.
A triangulare prism
A rectangle is a two dimensional figure having two dimensions aslength (L)bredth(B) But in the cased of three dimensional figure having three dimensions(one extra dimension as)height(H)So this figure having three dimension is called as Cuboid
TRUE for 2-dimensional figure. False for 3-dimensional figures.
A tetrahedron is a three-dimensional figure with four equilateral triangles. Every pyramid with a triangle as the base is a tetrahedron.
