Step-by-step explanation:
The first statement is correct. The volume of this rectangular prism is v = l*w*h, and so 495 cm^3 = (12*2.5 cm^2)*h is correct.
To find h, Zoe should divide 495 cm^3 by (12*2.5 cm^2), so the second statement is wrong.
The third statement is incorrect, due to an arithmetic error. 495 cm^3 divided by (12*2.5 cm^2) is 16.5 cm, not 15.5 cm. Thus: the missing height, h, is 16.5 c.m.
