How to Find the Volume of a Rectangular Prism. A rectangular prism has three dimensions: length (l), width (w), and height (h). A rectangular prism has volume formula V = lwh. So, for example, if a rectangular prism has dimensions l = 12 in., w = 4 in., and h = 3 in., then V = 12 in. x 4 in. x 3 in.
Volume and Surface Area Study Guide Volume Volume of a Rectangular Prism = (length x width x height) Volume of a Triangular Prism = (area of the base x height of the prism) Surface Area Surface Area of Rectangular Prisms, Triangular Prisms and Pyramids = find the area of all the faces then add them up. Rectangular Prisms: 6 faces (front, back, left, right, top and bottom) All faces are rectangles to find the area multiple length x width of each rectangle and add them all up. Triangular Prisms: 5 faces (two triangles and three rectangles) Find the area of the two triangles A= then find the area of the three rectangles and add them up.
