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)
