The prism that has 3 pairs of congruent sides is called a rectangular prism. It is also known as a cuboid. To visualize a rectangular prism, think of a shoebox or a book. It has six rectangular faces, and each pair of opposite faces is congruent. This means that the length and width of one face are equal to the length and width of the opposite face, respectively. Additionally, the height of the prism can be any value, as long as the bases are rectangles.
