The volume of square pyramid is 141 2/3 cubic inches. the height of the pyramid is two more than three times the lenght of its base . what is the lenght of the base?

solve for "x"

hmm I tried factoring it, tried a few combos, no dice, haven't graphed it

but, it doesn't seem it factor that neatly, so the solutions are likely decimals with long floats

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
