Use surface area formula: Surface area \(=2(wh+lw+lh)\) This formula is derived by considering that the parallel faces in a rectangular prism have the same area. h is the length of the height of the prism. l is the length of the width of the prism. Volume of Rectangle Prisms Surface Area of a Rectangle Prism Rectangular Prisms – Example 1:įind the volume and surface area of the following rectangular prism.įind the volume and surface area of rectangular prism. The formula for the surface area of this rectangular prism is: A S 2 ( b l + l h + h b) where, b is the length of the base. Surface area of a Rectangular prism \(=2(wh+lw+lh)\).Volume of a Rectangular prism \(= l×w×h \),.Volume of a Rectangular prism \(=\) Length \(×\) Width \(×\) Height.
Now since it is composed of all rectangular faces, and the area of a rectangle is given by the product of its length and width, add up all the products of lengths and breadths to conjure up the surface area of a rectangular prism.
