I'm not sure, but I think you would find the are of the base and find the area of one of the triangles and multiply the triangle one by four...I am basing this off of my 5th grade math lessons in surface area, so this may not be accurate...but you can try it and find out for me! :D
If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
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
It depends on the dimensions of the base and the height (slant or vertical) of the pyramid.
The volume of a triangular pyramid can be found using the formula Volume=Base Area x height /3. Surface Area can be expressed as Surface Area =Base Area+0.5 x perimeter x side length.
The formula for a square pyramid is one square attached to four triangles which meet at a point.There are other formulae for the surface area or for the volume.
This is a popular topic, discussed in many places on the web. The attached link is one place that I like. If you want to look for others just google for surface area square pyramid.
The formula to find the area of an octagonal pyramid is area of base plus area of sides.
If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
A pyramid with these measurements are technically impossible to construct. However if you follow the formula the surface area would be a negative amount.
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
The answer depends on the what characteristic of the pyramid you want the formula for: its surface area, its volume or something else.
It is: base area+(4*triangle areas)
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
It depends on the dimensions of the base and the height (slant or vertical) of the pyramid.
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
