In this video, you will learn how to find the surface area of rectangular prisms, by analyzing the prism’s six faces and computing their areas.

area of a rectangle – computed by multiplying length times width (A = L x W)

rectangular prism – a 3D solid with six faces that are rectangles

surface area – the sum of the areas of the faces of a 3D solid

2 small faces

2 medium faces

2 large faces

Surface Area of a Rectangular Prism = Sm. Rec + Sm. Rec + Med. Rec + Med. Rec + Lg. Rec + Lg. Rec
