It has to do with the surface area formula:
To find the total surface area of a pyramid, use this equation:
Surface Area = B + 1/2 * P * s
B = base area
P = perimeter of the base
s = slant height
To find the volume of a Pyramid, substitute into this equation:
V=1/3Bh
B=base area
h=height of pyramid
Volume = 1/3 height of pyramid multiplied by the area of the triangular base. V = 1/3 h * area of base.
from a pyramid
The answer depends on the what characteristic of the pyramid you want the formula for: its surface area, its volume or something else.
The general formula for any type of pyramid - as well as for cones - is (1/3)Bh, where "B" is the base area, and "h" is the perpendicular height.
The answer depends on what information you do have about the pyramid.
first you find the area of the base and then you find the area one side of the pyramid an you time it with 3 if it is a triangular pyramid or 4 if it is a square pyramid
The formula to find the area of an octagonal pyramid is area of base plus area of sides.
Find The Area Of Base and The Four 'Faces' and add them together.
Volume = 1/3 height of pyramid multiplied by the area of the triangular base. V = 1/3 h * area of base.
from a pyramid
The formula is: V=â…“ . bh, where: b - area of the base h - height
1/3 b x h b=area of base h=height of pyramid
The answer depends on the what characteristic of the pyramid you want the formula for: its surface area, its volume or something else.
Use the formula 1/2bh to find the area of a triangle side. Then multiply that by 6 because you have 6 sides on the base.
Add the area of the base to the combined area of the faces Or just do this formula: PIxradius squared+ PIxradiusxThe slant height (if it is given)
The formula for a triangle-base pyramid (a form of tetrahedron) isV = 1/3 Bh where B is the area of the triangular baseFind the area of the base by the formula B = 1/2 bh (height of that triangle), then multiply by 1/3 of the pyramid'sheight.
