(B) \(512\text{ cm}^3\)
(C) \(384\text{ cm}^3\)
(D) \(64\text{ cm}^3\)
Correct Answer: (B) \(512\text{ cm}^3\)
Explanation:
$$\text{Volume of a Cube} = a^3$$
Given edge \(a = 8\text{ cm}\): $$\text{Volume} = 8^3 = 8 \times 8 \times 8 = 512\text{ cm}^3\ (\text{ .})$$
Question 02
The length, breadth, and height of a cuboidal box are \(15\text{ cm}\), \(12\text{ cm}\), and \(8\text{ cm}\) respectively. Find its volume.
