If the base is a rectangle, use the formula for the area of a rectangle.
The formula will depend on what it is that you are trying to find: the volume or the surface area.
The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism. This formula calculates the total area of all six faces of the rectangular prism. It is derived from the formula for the surface area of a box, which consists of three pairs of identical rectangular faces.
The surface area of a rectangular prism can be calculated by adding the areas of all six faces. The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively. This formula accounts for the two faces of each dimension (length, width, and height) on the rectangular prism.
A= 2(wh+lw+lh) where w = width h = height and l = length When trying to find the surface area of something, it is important to try to remember the specific formula. The formula for the surface area of a rectangular prism is A=2(wl+hl+hw).
u have to find the surface area for individual sides. so lxw for each individual side
surface area=(perimeter of base)x(height of the shape)+(area of the base)x(2)
LxWx2
Suppose that the area of the rectangular base is: lw then if the height is: h the surface area is: lw + lh + wh I believe that formula is for the surface area of a rectangular prism...
The formula for a rectangle is height x width (A=ab)Since you said surface area, I'm pretty sure that you might mean a rectangular prism. To get this, you would need to find the area of each "rectangle side". To do this, you use the first formula, using height (a), width (b), and depth (c). The formula for theSurface Area of a Rectangular Prism = 2ab + 2bc + 2ac
A rectanglar or even rectangular, is an adjective and there is no such thing. You can have a rectangular pyramid or a rectangular prism. The formula will depend on which of these it is and on what information is available to you.
I am not sure that a rectangular prism is in any position to care!
