if I have 706,700 square miles how many miles do I have

If there are 706,700 square miles, there are 706,700 miles in one direction say east - west and 706,700 miles in the north-south direction. Thus 706,7002. Multiply 706,700 by itself to arrive at your answer, 499,424,890,000 miles.

Your question doesn't make sense. Square miles is a measure of area, while miles is a measure of length. I can make 706,700 square miles many different ways. Here are a few:

A rectangle that is 70,670 miles long by 10 miles wide (area = L*W = 70,670*10 = 706,700)
A rectangle that is 7067 miles long by 100 miles wide (area = L*W = 7067*100 = 706,700)
A triangle with a base of 14134 miles and a height of 100 miles (area = (1/2)*base*height)
A square that is 840.65 miles by 840.65 miles (area = side2 = 840.652 = 706,700)

Miles square[edit]

Square miles should not be confused with miles square, a square region with each side having a length of the value given. For example, a region which is 20 miles square (20 mi × 20 mi) has an area of 400 sq mi; a rectangle of measuring 10 mi × 40 mi also has an area of 400 sq mi, but is not 20 miles square.

Section[edit]

In the United States Public Land Survey System, "square mile" is an informal synonym for section.
