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.
You need some information about the height of the pyramid and the formula will depend on whether you have the vertical height or the slant height or the length of a lateral edge.
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.
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.
The formula is: V=â…“ . bh, where: b - area of the base h - height
from a pyramid
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 answer depends on the what characteristic of the pyramid you want the formula for: its surface area, its volume or something else.
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.
