Novay_Z [31]

Answer:

Factors that will affect the weight of box and those which will not affect the weight have been described below under different headings-

Step-by-step explanation:

Factors affecting weight of the box -

  • Size - the larger the will be the size of the box, more will be its weight.
  • Material - the material used to make the box will also influence the weight because if lighter material is used then the weight of the box will be less as compared to the heavier material.
  • Contents inside the box - if there are more contents filled in the box then it will increase the weight of box.

Factors that will not affect the weight of box -

  • Colour - whatever be the colour of box, weight will not be influenced by it.
  • Shape - the shape will also have no effect on weight cause it only denotes how the material is arranged to make the box.
  • Design/Graphics - designs made on the box to make it more attractive will also have no effect on the weight of the box.
