What is the mathematical formula for calculating the surface area of a truncated pyramid?
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.
What is the official name for an 11 sided Pyramid?
A decagon based pyramid. It is a hendecahedron but that can take many shapes. A nonagon based prism, for example.
Which part of the regular pyramid formula is for the pyramids lateral area?
The answer to this question depends on what sort of pyramid it is, and that depends on the shape of the base. You can get triangular pyramids (with a triangular base), square pyramids (like those in Egypt), pentagonal pyramids and so on. Let me take just one -- the square pyramid. Let the length of the base sides be 'a' units. Let 'h' units be the perpendicular height (i.e. at right angles to the base and going through the peak of the pyramid) of each side. I gather by lateral area that you mean surface area including the base. I use the symbol * to mean x or multiply. Then the formula for working out the surface area is a*a for the base PLUS each triangular face is 1/2*a*h There are 4 triangular sides so the surface area is (a*a) + 4*(1/2*a*h) If you just want the 4 sides, leave out a*a.
How much 2ft by 2ft tile does it take to cover the floor of an area 3000 square feet?
750, if you need no extra!
Why do you need surface area for?
In the biological world the surface area ratio to the volume determines if a cell will explode. The reason salt can cause swelling or the death of plants.Paint is a more common use of surface area. How much paint will it take to cover a room 12x12x8 with the ceiling but not the floor.
