Ques: Identify a solid that has a volume of 32 cubic units.

     example of Cubic Unit
    Choices:
    A. Figure 1
    B. Figure 2
    C. Figure 3
    D. Figure 4
    Correct Answer: D

Solution:

    Step 1: Volume of the rectangular solid = l � w � h
    Step 2: For Figure 1, Volume V = 6 � 3 � 4 = 72 cubic units
    Step 3: For Figure 2, Volume V = 5 � 3 � 4 = 60 cubic units
    Step 4: For Figure 3, Volume V = 4 � 3 � 5 = 60 cubic units
    Step 5: For Figure 4, Volume V = 2 � 4 � 4 = 32 cubic units
    Step 6: Hence, Figure 4 represents a solid that has a volume of 32 cubic units.
