It could be the length.
Surface area of any pyramid is 1/2Pl + B; where P=perimeter of the base, l=slant height and B= Area of the base.
a rectangular pyramid has a rectangular base and two pairs of congruent triangle sides. Given the height of the pyramid as well as its length and width, the area equals (l * w) + (l * (sq. rt ((w/2)^2 + h^2)) + (w * (sq. rt ((l/2)^2 + h^2)).
P*H+2*(L*B) Perimeter*Height+2*(lenght*Breadth)
To determine the surface area of a period (right rectangular), there is a unique formula. It is lw+l to the square root of w/2 squared + h squared + w square root of (l/2) squared + h squared. L=Length, W=Width, H=Height.
It could be the length.
SA = s2 + 2 × s × l
Surface area of any pyramid is 1/2Pl + B; where P=perimeter of the base, l=slant height and B= Area of the base.
Surface area of a triangular pyramid: SA = 1/2 as + 3/2 sl a = altitude of the base triangle s = side of the triangle l = slant height of the pyramid.
a rectangular pyramid has a rectangular base and two pairs of congruent triangle sides. Given the height of the pyramid as well as its length and width, the area equals (l * w) + (l * (sq. rt ((w/2)^2 + h^2)) + (w * (sq. rt ((l/2)^2 + h^2)).
P*H+2*(L*B) Perimeter*Height+2*(lenght*Breadth)
To determine the surface area of a period (right rectangular), there is a unique formula. It is lw+l to the square root of w/2 squared + h squared + w square root of (l/2) squared + h squared. L=Length, W=Width, H=Height.
Call the length of the base s and the slant height of one triangle l SA = s2 + 2sl
The surface area is L*B where L is the length of the rectangle and B is the breadth.
"Surface area" is the covering of a multi-dimensional body. It is the area that the outside of a body has.For exampleA cube has a surface area of 6 * L2 where L is the length of one side. (six sides to the cube, each is a square with area L * L)
The question asks about the "pyramid shown". In those circumstances would it be too much to expect that you make sure that there is something that is shown?
2*pi*r^2*L= Surface Area this is wrong!
