well 18 tons will do a pad 20X20 4 inches thick... which is almost 1/2 a ton per square foot at 4 inches thick. so 1 ton per 8 inches thick per square foot. so I would say around 42 tons of crusher for your pad.
You say 12'x12 `—> that ' is the sign for feet. so if the patio is 12 feet by 12 feet then it is 144 square feet. You don't say what measurement the "4 thick" is, but I presume it is inches. 4 inches is 1/3 of a foot, so divide the square footage by 3 and that will give you the cubic footage - if the patio is 12 feet by 12 feet and 4 inches thick then the cubic footage is 48.
It varies based on the design. Some are very small, but they are classified. One that I worked on, a BWR, had a reactor pressure vessel that was 20 feet in diameter, 80 feet long, and 6 inches thick. The active fuel region, however, was only 12 feet long.
around 13ft 1.5 inches
2 feet 6 inches
yes, it is. 40 tonnes converts to about 39 tons, or 78,000 pounds.
5ton
36 tonnes
It will cover 174 square feet of area.Hope this helps
You will require 111.6 imperial tons.
You will need about 3.7 cubic yards (around 4.75 tons) of gravel.
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
That is 104.16 feet.
36x36x36 inches or 3x3x3 feet or 27 cubic feet. If applied a foot thick, it will cover 27 square feet; 6 inches thick = 54 square feet (e.g.: an area 9 feet by 6 feet); 3 inches thick = 81 square feet (e.g.: an area 9 feet by 9 feet).
One yard will cover 81 square feet 4 inches thick, So 81x40=3,240 square feet if spread 4 inches thick. 36/4=9, 9x3x3=81, 81x40=3,240 If you want it 6 inches thick 36/6=6, 6x3x3=54, So one yard will cover 54 square feet 6 inches thick, And 54x40=2,160 square feet If spread 6 inches thick! Now this is spreading it on thick/DEEP!
250 feet times 8 feet is 2000sqft, times one inch thick is 166.67 cuft. 166.67 cuft is 6.17 yards. Stone weight approximately 1.25 tons per yard. Therefore, at an inch thick, you need 7.71 tons of pea gravel. 250 feet times 8 feet is 2000sqft, times one inch thick is 166.67 cuft. 166.67 cuft is 6.17 yards.

It depends on what "5 thick" is: 5 inches thick, 5 feet thick, 5 yards thick, 5 miles thick etc.
That would depend on how deep you want the dirt to be... to cover an area that size with dirt just one inch thick...you'll probably need around 20 tons....so multiply by 20 tons however many inches thick you'll need it
