**Solved Example on Cubic Unit**

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.
