How many 2 by 2 squares are there on an 8 by 8 chessboard?
64 squares on the chess board, and 4 squares in a 2 x 2 square; 64 / 4 = 16.
Lumber - How do you calculate board feet?
Though "board foot" sounds a measurement of area it is actually a measurement of volume. 1 board foot equals 144 cubic inches of wood. Length x Width x Thickness = Board Feet Therefore a board that is 12 inches x 12 inches x 1 inch is 1 board foot. But so is a board that is 12 x 6 x 2 However, you must take into account the fact that all lumber is actually a different size than it says it is. A 2 x 12 is actually 1-1/2 by 11-1/2. So instead of a board foot of 1 x 12 being 12 inches long, it would be: 144 / (3/4 x 11-1/2) or 13.22 inches long.

Trees - How do you calculate board feet?
Understanding board feet is to know that: A 1" thick board that measures 12" wide, or 1 foot wide, and measures 12" long, or one foot long, is equal to one board foot. (1" x 12" x 12") The measurements for true board feet are measured and calculated by the true end size and length of the material. In construction, there arises a dichotomy, often causing confusion with understanding board feet and calculating board feet. For example, most dimensional lumber including 2 x 4's and 2 x 6's used to frame a conventional house do not measure end size at a full 2" x 4" or, 2 x 6". Rather, they measure 1 1/2" x 3 1/2" and 1 1/2" x 5 1/2" respectively.. As an another example of this dichotomy is, the flooring Contractor who will usually measure in square feet for the job but is faced with ordering 3/4" x 3 1/2" oak tongue and groove flooring that is supplied by the board foot, in this case 3/4" thick material is usually made starting with a 1" thick board. Hence, you are carged for 1000 board feet when the actual measured board feet of the finished material totals something more like 850 board feet. I can work through the formulae with you if you are working with material that is 3/8" thick, or 2 3/4" thick. Basically it is thickness times width times length with consideration for the true end size and length measures.

-9x5 over the square root of x plus 4?
(-9x^2/√x) + 4= [-9x^2/x^(1/2)] + 4= (-9x^2)[x^(-1/2)] + 4= -9x^[2 + (-1/2)] + 4= -9x^(2 - 1/2) + 4= -9x^(3/2) + 4= -9√x^3 + 4= -9√[(x^2)(x)] + 4= -9x√x + 4Or,(-9x^2/√x) + 4= [(-9x^2)(√x)/(√x)(√x)] + 4= [(-9x^2)(√x)/√x^2] + 4= [-9(x)(x)(√x)/x] + 4 simplify x= -9x√x + 4
