Showing working for a file-size calculation earns method credit when you:
A. Substitute the figures into the formula with the units visible at each step✓ 答案
B. Circle a final guess without showing the substitution
C. Omit the division by 8 without comment
D. Give only the answer with no units
解說
Method marks come from the substitution and the steps, so write width x height x depth, then the division by 8, then the answer in bytes or kilobytes. A correct number with no working can still lose the method marks.
