Measure the length and the width. Or if you are feeling particularly energetic, then one of them and the diagonal.

The answer will depend on what 640 is meant to measure: area, perimeter, length of diagonal. Who knows? Especially when no units are given. It is, therefore, impossible to give a sensible answer to this question.

Please clarify what linear measure you want to calculate: for example its length, width, diagonal, perimeter, etc.

A "perimeter" is a 2D measurement and cannot be applied to a 3D object. However, sometimes the area around a building or piece of property to be protected is known as a perimeter. In that case, measure the sides of the facet of the object facing the ground, add them up and you have a perimeter. "Surface area" would be the closest thing to a perimeter, purely speaking. Measure the area of one facet of an regular 3D object (such as a cube), multiply that number by the number of facets, and you get the surface area.

Perimeter is in feet and not in square feet

If the perimeter measure 20" then each side is of length 5". Let D be the diagonal. Using Pythagoras' Theorem. D² = 5² + 5² = 25 + 25 = 50 Then D = √50 = 5√2 = 7.071" (3dp)
