Solved Example on Cubic Unit

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

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
