i have an answer for both a frustum of a pyramid and a frustum of a cone which do you need frustum of a cone just give both of them

It depends on the surface area of what!

To find the perpendicular height of a square pyramid, first compute for the volume of the pyramid. Then divide the volume by the area of the base to find pyramid's height.

Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.

Hexagonal prisms cannot be regular. If you tried to make one it would end up being a hexagon since six equilateral triangles make a hexagon. Therefore, there is no surface area.

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

You can find the exact surface area for all of those shapes.

The surface area of a pyramid is the area of all the faces of the pyramid, for a pyramid with apex in the centre and a regular polygon as its base, (the bottom of a pyramid is the base, it is regular if all sides are the same length) the surface area is: B + 1/2(P * H) where B is the area of the base, P is the perimeter (area around) the base and H is the height of the pyramid.

Surface area of any pyramid is 1/2Pl + B; where P=perimeter of the base, l=slant height and B= Area of the base.

Find the surface area of each of the four triangular faces (they need not be the same) and sum the individual areas.

An octagonal pyramid has nine faces. It also has nine vertices and 16 edges. You can find the volume of this pyramid by using the formula that the base 'B' multiplied by the height 'h' must be divided by three.

If its a triangular based pyramid (tetrahedron) then it will have 4 equilateral triangle faces and so find the area of one face and multiply it by 4 to give the total surface area.
