Please help me it’s overdue

The surface area A of a cube is equal to the sum on the areas of the 6 square faces that form the cube. If each face has side length s, then the formula A=6s2 can be used to find the surface area of a cube. The surface area of the cube shown is 1944 units2. What is the value of x?

    Answer:

    Step-by-step explanation:

    Given that,

    The surface Area of a cube is equal to the sum of the 6 Square faces

    And each side has a length of ‘s’

    Formula to calculate the surface area is

    A = 6s²

    Given that the surface area is 1944 units²

    It is a straight forward question,

    The questions already gave us the formula for area of a cube and which is 6s² and the question said that if the area is 1944 unit², find ‘s’

    So,

    A = 1944

    6s² = 1944

    s² = 1944 / 6

    s² = 324

    s = √324

    s = 18 units

    So, the value of s- is 18 units
