How do you figure up how many cinder blocks you need?

Calculate the exterior face area of he wall you want to build and the face area of the side of the cinder block (add about 1/2 inch to length and 12 inch to width for mortar thickness). Divide the wall area by the block area This is the number of blocks you require. This is how I figure out how many blocks you will need: First measure the length of walls for the blocks in feet. Second divide that number by 4 then multiply the total by 3. That will give you total blocks needed for one course of blocks.


If the moon hits your eye like a big pizza pie what will a cinder block do?

Figure out the circumference of a february moon.Then figure out the square footage of a cinder block.(for discussion purposes we will use the kind with three holes,a solid one will give a different answer).Add these two answers together and divide by the circumference of a pizza(you will get different answers for different types of pizzas.For discussion purposes we will use a 12 inch pizza).Figure out the velocity of flight of a cinder block being thrown off the top of a Papa Ginos on top of the face of a 27 year old man.Add this figure to the speed of a pizza being thrown like a frisbee at the face of the same 27 year old(12 inch pizza).Divide that answer to the distance of the empire state building to times square and that should answer your question.remember the answer will vary with different size pizzas and cinder blocks.If that doesnt work,throw a cinder block at your next dor neighbors bratty son and you may figure it out.Then go out to Chuck e cheese and buy him a pizza to keep his mother from suing you.Of course I may be wrong! Restraining order, it'll give you a restraining order. ;)
