Rectangular prism
A prism is two polygons, or multiple-sided closed shapes, joined together to form an enclosed three-dimensional shape. For example, a box is a prism because it consists of two squares or rectangles joined together to make the enclosed three-dimensional figure seen here:
Two-dimensional shapes make the flat top and bottom sides, or faces, of a prism.
So any box, stacks of Post-It Notes, and even legal pads are all prisms because they're three-dimensional objects with congruent polygons as faces.Two-dimensional shapes make the flat top and bottom sides, or faces, of a prism.
Formulae used
l = length of the rectangular prism
b =width of the rectangular prism
h = height of the rectangular prism
v = volume of the rectangular prism
s = surface area of the rectangular prism
a = area of the base
v = l * b * h
s = 2(lh + lb + bh)
a = l*b
\[diagonal = \sqrt{l^{2}+b^{2}+h^{2}} \]
