You have to visualize the 3-D object. Think in your mind that this object has six sides. To find the surface area you need to add all of the areas of these sides together. In order to do that you need this formula...
S.A. = 2(L*H) + 2(L*W) + 2(H*W)
L=length
H=height
W=width

The formula for the surface area of a rectangular solid is = 2lw + 2lh + 2wh 2(length x width)+2(length x height)+2(width x height)
LxWx2
To calculate the surface area of a solid, you need to know the shape and dimensions of the solid. For example, the surface area of a rectangular prism can be found using the formula (2(lw + lh + wh)), where (l), (w), and (h) are the length, width, and height, respectively. For a sphere, the formula is (4\pi r^2), where (r) is the radius. Please provide the specific dimensions and shape of the solid for a precise calculation.
You mean a rectangular prism? Like a block of lego? Then you just need to work out the surface area of the four sides, which will be two pairs of identical rectangles. So; ((L*W)+(W*D))*2 L ______|______ / /| /____________/ |-D | | | | | / |____________|/ \ W
To find the surface area of a rectangular prism, use the formula ( SA = 2lw + 2lh + 2wh ), where ( l ) is the length, ( w ) is the width, and ( h ) is the height of the prism. This formula calculates the area of all six rectangular faces. Simply plug in the dimensions of the prism to compute the total surface area.
The formula for the surface area of a rectangular solid is = 2lw + 2lh + 2wh 2(length x width)+2(length x height)+2(width x height)
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...
LxWx2
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.
Surface area = 2LW + 2(L+W)H
2lw + 2lh + 2wh
its not i dont no why

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).
Formula: S = 2B + L
I am not sure that a rectangular prism is in any position to care!
The formula will depend on what it is that you are trying to find: the volume or the surface area.
