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
