Total surface area of cube is 54 cm2. Then its side is ………… cm.A) 6 B) 9 C) 12 D) 3 |
|
Answer» Correct option is: D) 3 Let side of the cube be a. \(\therefore\) T..S.A of the cube is 6 \(a^2\) Given that T.S.A of the cube is 54 \(cm^2\) . \(\therefore\) 6 \(a^2\) = 54 = \(a^2\) = \(\frac {54}6 = 9 = 3^2\) \(\therefore\) a = 3 cm Hence, the side of the cube is 3 cm. Correct option is: D) 3 |
