What is 3d rectangle?

A 3D rectangle, also known as a rectangular prism, is a three-dimensional shape that has six faces, with opposite faces being congruent and parallel. It has eight vertices and twelve edges.

The formula to calculate the volume of a 3D rectangle is V = l x w x h, where l is the length, w is the width, and h is the height of the rectangle.

The surface area of a 3D rectangle can be calculated using the formula SA = 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height of the rectangle respectively.
