Average mature trees are from 200 to 240 feet high with diameters of 10 to 15 feet at 4 feet 8 inches above the ground. Exceptional individuals sometimes reach a height of 350 feet, a diameter of over 20 feet, and an age of approximately 2000 years. Redwood leaves are green, flat, and sharp-pointed.
Given 3a/(a+1)^2 To make the denominator a cube, you would have to multiply by 1 or (a+1)/(a+1) yielding 3a(a+1)/(a+1)^3 (3a^2 + 3a) is the equivalent numerator
