What is 2100 as a product of primes?
To express 2100 as a product of primes, we need to find its prime factors. First, we divide 2100 by the smallest prime number, 2, to get 1050. Then, we continue dividing by 2 until we can no longer divide evenly. The prime factorization of 2100 is 2^2 x 3 x 5^2 x 7.
How many BTU would it take to cool a home down of 4200 square feet with a central air conditioning system?
The only sure way to tell you is to do a heat load calculation on your 4200 ft2 home. Such things as windows, insulation values and other factors effect the size of the unit or units that you would need.
How do you find out how much insulation you would need for a shop with 10 foot walls measuring 26 feet by 28 feet built with 2X6 16 inches on center?
Multiply the height of the wall space by the length. This will give you the square footage. Rolls of faced and unfaced insulation are generally sold by square footage. Make sure you take out for windows and doors (especially the overhead garage door).
How many cubic feet of insulation do you need to cover 200 sq ft 12 inches deep?
200 cubic feet.
What size air conditioner do you need for 2800 square Feet?
It depends on your location, shade, windows, and insulation. You should be able to find a local A/C contractor who will do what's called a J-load calculation. There are also online calculators that will give you a rough approximation if you have an idea of how good your insulation and windows are.
