Questions and Answers

Can the volume of a cylinder be calculated by multiplying the area of its base by its height?

  • No, because the volume of a cylinder is not related to the area of its base.
  • Yes, because the top and base of a cylinder are congruent and parallel to each other.
  • No, because a cylinder has curved surfaces that affect the volume calculation differently. (correct)
  • Yes, because the lateral surface of a cylinder is perpendicular to the base.

    • If two cuboids have the same volume, can they have different total surface areas?

  • Yes, because total surface area depends on the dimensions of the cuboid. (correct)
  • No, because same volume implies same surface area.
  • No, because total surface area is directly proportional to volume.
  • Yes, because total surface area is not related to volume.

    • What is used to calculate the total surface area of a cuboid?

  • The length and width of the base only.
  • The length and height of the cuboid only.
  • The product of all three dimensions.
  • The sum of areas of all its faces. (correct)
