A cube has an edge of 6 cm. Consider the following statements:
I. The volume of the cube is 216 cm3.
II. The total surface area of the cube is 216 cm2.
Which of the above statements is/are correct?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Both I and II
For a cube of edge \(a\): volume \(=a^3\) and total surface area \(=6a^2\) (six square faces).
Statement I — Correct.
Volume \(=6^3=216\) cm3
Statement II — Correct.
Total surface area \(=6\times6^2=6\times36=216\) cm2
Both statements are correct. (For a cube of edge 6 cm the two numbers happen to be equal, though the units differ.)
