The marginal utility of the third slice is calculated by subtracting the total utility of two slices (10) from the total utility of three slices (14), which equals 4. The marginal utility of the fourth slice is found by subtracting the total utility of three slices (14) from the total utility of four slices (20), which equals 6.
