The formula to find the area of an octagonal pyramid is area of base plus area of sides.
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.
You can find the exact surface area for all of those shapes.
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.
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.
Find the surface area of each individual face and then add them together to give the total surface area 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
Find The Area Of Base and The Four 'Faces' and add them together.
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
Find the area of one of the sides and then multiply it by 3 (3 sides to a triangular pyramid)Then work out the area of the base of the pyramid, and add it to the total area of all the sides.Area of a triangle = Base x Height / 2
To calculate the surface area of a truncated pyramid, you first take the surface area of each side. That would be the base time the straight height. If it is a 4 side pyramid with equivelant sides, multiply that answer by 4.
There is not enough information to answer the question.
Figure it out stupid.
Using the dimensions you're given and those that you can calculate . . .-- Calculate and write down the area of each face of the pyramid.-- Then add up all of the individual areas.-- The sum is the surface area of the pyramid.
That is not true: for a pyramid, for example.
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
s+s+s+s+b=area of pyramid
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
Surface Area= 1/2perimeter x slant height + B * * * * * Perimeter = perimeter of base. B = Area of base.
It is 288 cm^2.
Area = B + ( (PH)/2 ) Where B is the base area, P is the base perimeter and H is the piramid height.
To find the height of the triangles on the sides of the pyramid, we use pythagorean theorem. We slice vertically through the center of the pyramid to find a triangle with base of 6.3 and height of 4. Using the pythagorean theorem, we can find that each side of this triangle will be sqrt(42+3.152). This will be the height of the triangles on the sides of the pyramid, let's call it h.So, the area of each triangle will be 1/2*6.3*h. There are 4 of these triangles.The area of the base of the pyramid will be 6.32The total surface area of the pyramid will be SA = 2*6.3*sqrt(42+3.152)+6.32SA ~= 103.84 m2
