You really can't "prove" the formula. You use it. You first square the base 'b'. Then, you multiply that number by the height 'h'. Then, you divide the product of the base squared and height by 3. Boom! You get your answer. In my school, we get a formula sheet with all the formulas we will need to use. If you didn't understand the description above, here is the formula for a square pyramid:1/3b2 h.
Hope this helped!
This is easiest done with integral calculus. The basic idea is to divide the pyramid into lots of thin, flat, parallel slabs, calculate the volume of each, and add it up.
This is impossible to prove, as the square root of 2 is irrational.
Surface area of a hollow cylinder = 2*pi*radius*length measured in square units.
It is not possible to prove something that is not true. The square of 2 is rational, not irrational.
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
For example, you can take a look at the Pythagorean formula: c = square root of (a2 + b2).
Cool question ! Answer - half it then cube it to prove it - an example for you if cube diagonal (not square diagonal) is 100, then using pythagoras theorm the square diagonal = 70.71068, If square the square diagonal = 70.71068, then using pythagoras theorm the side length = 50 therefore the volume = 50 ^ 3 = 25000 units works with any numbers
its half a square and a square is 360
927,742. And I challange anyone to PROVE me wrong.
no be quiet
The volume of a cylinder is the area of its base's area times the height (you will prove this in Calculus). Thus the formula you need to use is: pi * radius^2 * height. I will let you do your own homework from there.
density = mass/volume volume = mass/density mass = volume*density Here are some numbers from a recent chem experiment that prove this. 4.360g/mL = 30g/6.88mL 6.88mL = 30g/4.360g/mL 30g = 6.88mL*4.360g/mL
