To find the area of 10 squares with side length 7 inches, we would calculate 10 * (7^2) = 10 * 49 = 490 square inches.

To find the remaining space for Robert's presentation, we would subtract this area from the total area of the poster board: 720 - 490 = 230 square inches.

Therefore, the correct answer is 230 square inches.
