The volume of a right rectangular prism is found by multiplying the area of the base by the height. In this case, the height is 17.5 centimeters and the area of the base is 18 square centimeters. Therefore, the volume is:
V = A × h
V = 18 cm² × 17.5 cm
V = 315 cm³
Therefore, the volume of the right rectangular prism is 315 cubic centimeters.
