Volume of the right rectangular prism, $V$, is the product of the, $A$, area of base and, $h$, height of the prism. The base of the rectangular prism is, rectangle. So the area of the base is product of length and breadth or width. The formula for finding the volume of right rectangular prism is $V$ = $lwh$.
Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac (a, b, and c are the lengths of the 3 sides) In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same. The area of the top and bottom (side lengths a and c) = a*c. Since there are two of them, you get 2ac. The front and back have side lengths of b and c. The area of one of them is b*c, and there are two of them, so the surface area of those two is 2bc.
