Rectangular Prism Surface Area Formula

The surface area of a rectangular prism is calculated by summing the areas of all six faces. The formula is derived from the basic geometric principles:

Surface Area = 2 × (Length×Width + Length×Height + Width×Height)

Length: The longest side of the rectangular prism
Width: The shorter side of the rectangular prism
Height: The vertical side of the rectangular prism
