(b)(2 pts) Enter the integer value of 

6(x  5)^{2} dx = 
[2]  (a)(1 pt) On the graph at the right, click those boxes located in the region R bounded by the curve y = x^{3} (red) and the line y = x (green). 


(b)(3 pts) Enter integers below (such as 4, 0, or 3) to express the
size of the region R (in question [2a] above) as one definite integral: It is possible to use 2 integrals, but here, use only one Scoring: Limits (just right of the integral sign) worth 1 point, and integrand (in parenthses) worth 2 points 



(c)(1 pt) Find the size of the region you drew in [2a] above by
evaluating the integral which you wrote as an answer in (2b) above. (size of R) =
