formula for required yars for 9'X12'X 4' deep
Avast 'er maty....only one yar required, 'or 'omethin that deep!
Andy replies:
9'X12'x4' is 432 cubic feetThere are 27 cubic feet per cubic yard.
Carry on,
Andy
That's a very thick slab.
Nick
Yeah, on the off chance it was 4" thick it is ((9*12)*(4/12))/27 or about
1 -1/3 yards
That's a Jimmy Hoffa slab.

It is usually good to calculate the number of cubic yards based on 25 cubic feet per yard, this avoids running short due to spillage and/or for extra deep spots that need more material. Running short can be quite a problem when trying to get it finished before it starts to set, so some overage is always better, unless you are buying from a truck that mixes it as you take it and you pay according to a meter on the truck.
Four FEET deep?
15.6Four inches?
1.32
Damn, that must be a BIG flag pole.
Shortcut ... 81 sq/ft per yard at 4" thick
Nice tip. Darrell
What is sad is all the tax dollars we give to fund public education. this is fifth grade math. I want my money back.

Remember, Ed. We now live in the liberal era. Whether you are stupid or not doesn't matter. It's most important that you don't feel bad about feeling stupid. Or make some stupid person feel bad about feeling stupid.
HTH.
Steve, who wants to go back to the old ways and days
There you go again Edwin :):)
The little dumb-asses feel good about themselves. Isn't that what really matters?

Yeah, try to get one of the High school genius' to count change back to you at the cash register. They can't do it.
I particularly like it when they wad it into a semi ball and drop it all in your hands, bills, change, and all.

My first thoughts when I saw the OP
God help us!

Since when did public schools teach math?
They teach it. But it has "evolved" over time:
Evolution of the Math Problem
1960: A logger sells a truckload of lumber for $100. His cost of production is 4/5 of this price. What is his profit?1970 (traditional math): A logger sells a truckload of lumber for $100. His cost of production is 4/5 of this price, in other words $80. What is his profit?
1970 (new math): A logger exchanges a set L of lumber for a set M of money. The cardinality of set M is 100 and each element is worth $1. Make one hundred dots representing the elements of the set M. The set C is a subset of M and its complement is the set P. Circle the elements of the set P of profit.1980: A logger sells a truckload of wood for $100. His cost of production is $80 and his profit is $20. Your assignment: underline the number 20.
1990 (outcome based education): By cutting down beautiful forest trees, a logger makes $20. What do you think of this way of making a living? (Topic for class participation: How did the forest birds and squirrels feel?)2002: A logger sells a truckload of lumber for $100. His cost of production is $120. How does Arthur Andersen determine that his profit margin is $60?
I stopped after 1960. =20
I think a fifth is a pretty good deal ---- especially if it's Scotch = (Single Malt)
