55 gallons of water would weigh  55x 8.33lbs./gal  = 458.15 lbs Divide by  62.4 lbs per cubic foot (weight of one cf of water)  = 7.34 cf Divide by 27 = 0.27 cubic yards  or about 0.3 cubic yards.  That sounds low but if you consider a drum approx. 2 feet in diameter by about 3.0 feet tall (Wik says … Read more

Based on formula for area of equilateral triangle:  A=s^2 times square root of 3, over 4. Get rid of square root symbols.  25 times sq root of 3= 25 x 1.732 = 43.30 s^2 times square root of 3, over 4  therefore, equals 43.30 Cross multiply, becomes  s^2 times sq root of 3 = 173.20 Divide both sides by … Read more

It depends on the weight per cubic foot of the hot mix asphalt. An average weight might be 148 lbs/cf which would be 3,996 lbs per cy (148 x 27 cu ft/ per cy.) That would be about one ton equals 1/2 cy)

You have to know the weight per cubic foot of the hotmix asphalt.  That weight can vary greatly with the mix design. As a fairly accurate estimation it might weigh approx. 145 lbs./per cubic foot or so.  Now, if you have one ton (2000 lbs) and you divide 2000 lbs by 145 lbs./cf, you would have … Read more

Easiest way  is to convert 4 inches to yards (4/36 = 0.11 yards). Divide 30 cy by 0.11 is  272.73 square yards. So, it could be 273 yards long and 1 yard wide,   Or 16.52 yards square or any other two dimensions (in yards) that when multiplied together equal 273 sq. Yards. Or convert to feet and square … Read more

Objects that float weigh less than the amount of water they displace. Archimedes Principle (from Wik) "Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." Archimedes' principle does not consider the surface tension (capillarity) acting on the body.[2]

I don't know what your present situation is but if you have one always hot wire for two switches, make up two short jumpers (some say pigtails) long enough to reach from the hot to the switch. Splice the hot and two jumpers with a wire nut and hook the other ends of the hots … Read more

You have to know the weight per cubic foot of the dirt, and that weight varies with type of soil.  An average weight for dirt might be around 130 lbs per cf.  There are 27 cf in a cubic yard, so assuming 130 lb/cf times 27 is 3,510 pounds, divided by 2,000 is 1.76 tons … Read more
