Answer the question.A parcel delivery service lowered its prices and finds that it has delivered twice as many parcels this year as it did last year. To illustrate this fact, the manager draws a pictogram as shown below. Each cube depicts a parcel. The side length of the "parcel" on the right is twice the side length of the "parcel" on the left. ?
Why is this pictogram misleading? What visual impression is portrayed by the pictogram?
What will be an ideal response?
Answers will vary. Possible answer: The volume of the cube on the right is eight times (not twice) the volume of the cube on the left. The pictogram gives the visual impression that eight times as many parcels were delivered this year as last year.
