  1. Surface Area Formula: The surface area of a cube is calculated by the formula 6×side26 \times \text{side}^2. We know the surface area is 152cm2152 \, \text{cm}^2.
  2. Setting up Equation: Let's set up the equation: 6×(6x)2=1526 \times (6x)^2 = 152.
  3. Simplify Equation: First, simplify the equation: 6×36x2=1526 \times 36x^2 = 152.
  4. Isolate x2x^2 Term: Now, divide both sides by 66 to isolate the x2x^2 term: 36x2=152636x^2 = \frac{152}{6}.
  5. Calculate Right Side: Calculate the right side: 36x2=25.333336x^2 = 25.3333\ldots
  6. Solve for x2x^2: Next, divide both sides by 3636 to solve for x2x^2: x2=25.333336.x^2 = \frac{25.3333\ldots}{36}.
  7. Calculate Right Side: Calculate the right side: x2=0.7037x^2 = 0.7037\ldots
  8. Solve for x: Finally, take the square root of both sides to solve for x: x=0.7037x = \sqrt{0.7037}...
