You will build 3 different boxes with SQUARE bases. Click and drag the corner of the box to change it. Drag the point until the total measurement is 108.Then press the button below. I don't know how to find the girth (perimeter of base)

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36

Max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

Plzzz answer both questions and i will give you 100 points
