Suppose W/3 is the even integer X. Then the numbers are (X-2, X , X+2)If W/3 is not an even integer then there is no solution.
(w2)3 = w(2 x 3) = w6
Area = w2 - 6w + 9 = w2 - 3w - 3w + 9 = w(w-3) - 3(w-3) = (w-3)(w-3) It is clear after factorizing that the area given is of square of side: w-3 So, perimeter = 4 x side = 4 x (w-3) = 4w-12 units
The square footage of a space is equal to L x W, with L=length, and W=width. You have 3 feet x 3 feet. 3'=L and 3'=W. So LxW= 3'x3' which is 9 square feet. It is in square feet because it is an area and not a distance. (9ft2)
L x W x H = 3 x 3 x 3 = 27 cubic inches
