Free CT : GK (Ancient History) 10 Questions 10 Marks 6 Mins Given: Cubes ratio = 729 ∶ 512 Formula used: The volume of cubes = a3 The total surface area of the cube = 6a2 Where, a = Side of the cube Calculation: Let the side of the cubes are x and y respectively According to the question, x3/y3 = 729 ∶ 512 ⇒ x/y = 9/8 ⇒ x = (9/8)y The Ratio of total surface area = 6x2 ∶ 6y2 ⇒ 6 × (9y/8)2 ∶ 6y2 ⇒ (81/64) ∶ 1 ⇒ 81 : 64 ∴ The required ratio of the total surface area is 81 : 64.
