Can anyone figure the area of this shape?

Recommended Posts

I'm pouring concrete, and I need an accurate measurement of the area of this (square ffeet):

 

4' x 14'1 x 25'8 x 10'8 x 12'11

 

 

I know that you can, (and this is what I am actually doing), is divide the shape into squares and triangles, get the measurements of those. Then if you you need to, take the area of a "easy to work with"square or rectangle, then subtract the remaining triangle that you don't need....etc, etc, etc.

 

That's the way I am doing it, but you'd think there'd be a formula or calculator that you could punch those 5 numbers (listed above) into, and wham....have your answer.

no prob

 

its 36.2 square feet. hth

how did you come to that answer? it sounds way too small. :banana:

We would need to see the shape. :o

:banana:

Exactly

 

Along with those lengths we would need angles :o

Don't forget to subtract the area the body will take up.

no one is funny on this board, all the threads suck, and everyone here sucks at life... thats why we come here, we all have big cacks, bench 250 pounds 10 times, defer 15% into our 401ks, bed dozens of women each year, make 200k, etc

a five sided area? add up all the measurments and divide by 5 then multiply by 2 to get the area.

 

 

 

 

 

 

 

 

 

 

 

I have no idea, the triangle thing might work best

based on the info that we have...i come up with roughly 205 SF.

:mad:

 

Right around 200 somewhere.

I did a couple of different shaped in CAD and got areas between 95 and 130. I don't think there is a "right" answer without knowing the actual shape.

95? Really? I don't see how that could be.

 

4 of the 5 measurements are greater than 10 feet and one measurement is over 25 feet. A simple 4x25 rectangle would be more than 95 square feet.

 

:rolleyes:

It depends on the shape.

If its opened up it will be larger than if it is long and narrow.

Most conc companies will provide you with an estimating slide rule for free, if you ask.

Exactly

That's what my googling told me also.

 

I figured it the long way, and it came out to ~225 square feet. That's what I told the cement guy (who told me "You figure it out. That shape looks tough to figure out"

 

They are out pouring it now. *gulp*

 

 

You'd think you wouldn't need angles. Kinda like a piece of string in a circle. So long as you don't stretch the string, you can modify the shape however...like various sizes of ovals....and the area stays the same.

 

You'd think it would apply to an "irregular pentagon" also, but it doesn't.

how deep will the concrete be?

 

 

I wasn't looking for how many yards of cement...I can figure that out. I needed the area.
