Well, we know that the formula to find the surface area  of a rectangle is A = 2(wh + lw + lh). We plug in what we know.   SA (surface area) = 2948 in^2 l = 40 in w = 18 in h = ?   2948 = 2(18h + (40*18) +40h) (Multiply 40...

If you are doing this problem without a calculator, then you need to know that Π is rounded to 3.14 for practical purposes. The formula for the area of a circle (A) is A =Πr2. r = 6 ft   Π = 3.14, A = 3.14 x 62 A = 113.04 (which is an estimated answer because Π is estimated...

Sometimes it is easier to see it without so many words.  See if this helps some 250 = 250/1 So, your problem is 250/1 - 3/4. The common denominator for 1 and 4 is 4.  Therefore, you multiply: 250 x 4           1000 ¯¯¯¯‾‾ ...

I am thinking that this problem is stumping you because of the fraction 3/8.  It is a common problem for people.  Just remember that when you get the number with a variable alone on one side, all that you have to do is multiply both sides by the inverted number that is with the variable...

I would say that it is a rule for finding an unknown quantity as we use formulas to find answers.
