The correct answer is option C. The the volume of a rectangular solid is 532.836 cm³
Length of the rectangular solid = 11.4 cm
Breadth of the rectangular solid = 12.3 cm
Height of the rectangular solid = 3.8 cm
Therefore, the volume of a rectangular solid = l x b x h
= 11.4 cm x 12.3 cm x 3.8 cm
= 532.836 cm³
