The total surface area of a cube = 150. A. The length of one edge of the cube B. 4.5 In this question two quantities A and B are given. Compare the two quantities
Total surface area of the cube \(=6a^2\) \(a\) = side of the cube \(6a^2=150\) \(a^2=25\) \(a=5\) A. The length of one edge of the cube B. 4.5 So, quantity A is greater than quantity B.So the correct option is (A)
