Stone is approximated at about 2700 lbs. per cu. yd.
An acre is 43560 sq. ft.
8.5 acres is 370260 sq. ft.
There 9 sq.ft. per sq. yd., thus there are 41140 sq. yds. in 8.5 acres.
A cubic yard is 3 feet by 3 feet by 3 feet (LxWxH).
Since you are only going to be at 1.5 feet, each square yard is equal to 1/2 cubic yard, so to figure the cubic yards divide sq.yds. by 2, thus you get 20570 cu. yds. of stone.
20570 x 2700 = 55539000 pounds. Divide by 2000 to get tons:
55539000/2000 = 27769.5 tons.
First, you want to find out the square footage of the room. You do that by multiplying length times width. In your case, 14 x 12 feet would equal 168 sq/ft. Next, you multiply square feet by square meters with 1 sq/ft equaling 0.0929 sq/m. So, 168 times 0.0929 would equal 15.6072. If you google a conversion calculator for square feet to square meter , it will give you 15.6077. In other words, your room is just over 15 and 1/2 square meters. Hope this helped
Read size of air conditioner you need , each ton of air conditioning will keep cool 400 square.so higher ton yo pick you feel cool.please read below square feet to ton chart.
1 ton on 400 sq. ft.
2 ton on 800 sq. ft.
3 ton on 2000 sq. ft.
5 ton on 2570 sq. ft.
If you have a calculator just turn it on and typ[ what follows. [X] means you press the multiplication key [=] means you press the = key [+] means you press the addition key (plus)
16 [x]14 [=] area of first room.in square feet 14[X]5[=] area of second room.in square feet 13[X] 13= area of third room in square feet
If you want to obtain the total area of all the rooms at one go
that is a 10000 btu unit and a good rule of thumb to go by when 'sizing' a unit is 12000 btu for every 600 sq ft of cooling space (if the place is well insulated) or 400 sq ft (if not well insulated).
So, you have a 10000 btu unit which is 5/6th of 12000 btu - so - can reasonably expect that unit to cool approximately 500 sq feet.
In other words the room it's in now could be only - say - 300 sq feet (and well insulated) - in which case the AC unit is cooling it - well.
However, if you try to cool a 800 sq ft room - it will not work as well.
Hope this has helped.
Assuming the unit is 'cooling' but not cooling it 'well,' I would think the unit is too small.
NOTE: 2000 Btu for every 100 sq ft of cooling space if the room is well insulated. If not - then 2000 btu for every 66 sq ft.
For example - a 12000 btu AC unit should cool 600 sq feet of cooling space if well insulated.
or
400 sq feet if not well insulated.
hope this has helped.
The AC your landlord installed is rated at 8000 btu which is way too small for 900 sq ft. You need at least a 15000 Btu Air conditioner and a 'well insulated' house to be cool.
A good rule of thumb in the AC business says you need 1 ton (12000 btu) of Air conditioning for every 600 sq feet (if the house is well insulated) - if not - then you will need 1 ton (12000 btu) for every 400 sq feet.
So, if you have 900 sq feet and the house is well insulated you should have at least a 15000 btu unit.
If it's not well insulated you will need 24,000 btu.
