Answer 1

$\huge\underline\bold{\mathtt{\red{A{\pink{N{\green{S{\blue{W{\purple{E{\orange{R}}}}}}}}}}}}}$

The average grain size is calculated by the division of the number of intersections by the actual line length. Grain size average =1/number of intersections/actual length of the line. Actual line length = Measured length/ Magnification.

Answer 2
