A volume is described as follows: 1. the base is the region bounded by y = e ^ (3.9x); y = 3.9x ^ 2 + 0.7 and x = 1 ; 2. every cross section perpendicular to the x- axis is a square. Find the volume of this object. Note: for this problem, set up the integrand, but use your calculator to approximate the lower bound needed and use your calculator to approximate the value of the needed integral ( because we don't yet have the antiderivative tools we need to do this by hand). volume =
