Final answer:
The volume of the cuboid with dimensions 12 cm by 9 cm by 6 cm is 648 cm³, which is option (c).
Step-by-step explanation:
The volume of a cuboid can be calculated by multiplying its length, width, and height. Volume is the amount of space occupied by an object and is derived from its linear dimensions. For the given cuboid with dimensions 12 cm by 9 cm by 6 cm, the volume is calculated as follows:
Volume = length × width × height
Volume = 12 cm × 9 cm × 6 cm
Volume = 648 cm³
The correct answer is option (c) 648 cm³.
