1 cubic yard = 27 cubic feet. The 27 cubic feet come from the term cubic yard which think about it as a cube, go ahead and draw it. If all sides are 1 yard or 3 feet and you want to know how many cubic feet are in a cubic yard then you do a little bit of math. Which is 3ft x 3ft x 3ft = 27 cubic feet. Hopefully this helps.
Thank you very much for turning that 6 minute video into a paragraph that I understood completely. All due respect to the man in his dry erase board it is a nice one lol
I like his method of instruction because it can be easily shared with a classroom, as Jerry uses proper terminology. He is also using dimensional analysis in his final step. He followed up by adding approximately 5 to 10% for waste.
It's 160 the .32 is from him rounding up by using feet instead of inches and then converting back i.e. (144x480x4)%1728=160 But in all these you can imagine that the dig is not 100% level and there is always an estimated amount so 6 c.y. is still the answer in the end.
A real explanation would have been without cheating with a calculator. not much help in my opinion... and you should have explained that a Yard is equal to 3 feet, a cube is 3feet by 3 ft x3' = 27 (3x3=9)X3=27 to convert from cubic foot to cubic yards.
My head is spinning... surely there is an easier explanation. I mean this cancels that and that cancels this but no detailed explanation of where that that came from..
And while going through it all, think how better it would be to be able not to care about it at all (90%) and just buy precast costing 23% less for floors and 21% less for walls and how about that 5-10% on site pour waste factor? The math I did and the formula I will be using on a building I will be building is: If there is a structural choice = Buy Pre Stressed Precast.
Oh yeah by the way no concrete going to send you 6.23 yards or 6.35 yards it's either 6 yards or six and a half years or 5 and 1/2 yards so if you don't want to be short order an extra
It would be much easier if your measurements were converted to metric i.e. 12.2 m x 3.65m x .100m = 4.45 c.m. rounded up 4.5 m3 much simpler and less likely to make an error.
Bilal haider tanoli he rounds it to 6 because not every surface is leveled. there might be dips and there might be waste. its always good to have a little bit more extra than to end up needing more.
He didn't explain how to get one cubic yard. I believe its 3 x 3 x 3 = 27ft cu. 27 ft cubed = 1 cubic yard. So then he took the total of 160.32 ÷27= 5.9 yards cubed.
There is 27 cubic feet in one cubic yard ,,,,he did say they pour concrete in cubic yards ,,,, so if one yard is 27,,,then 160.32 cubic feet is 6 yards cubed
First, you know the area, 2nd you multiply the area by the depth or thickness 3rdly, you got the total volume in cubic metres Next, you obtain the weight for cement, sand and coarse aggregate or chipping by using ration 0.5:1:2:4 (BS8110). Where 0.5 is ratio of water, 1 is ratio of cement 2 is ratio of sand and 4 is ratio of coarse aggregates or chippings See More from @t
