Correct.
Area equals 30 by 26 equals 780 sq in; 780 divided by 144 equals 5.42 square feet, which meets the 5.0 square feet minimum allowed for grade-floor openings, and the 26 in height and 30 in width exceed the 24 in and 20 in minimums. The 5.7 square feet figure applies to openings not at grade floor. 30 in is not a height minimum; the minimum net clear height is 24 in. Sash size is not the measure, because the code regulates the net clear opening, and measuring the sash is a common error.
