    7.1ft

    Step-by-step explanation:

    The formula for calculating the total surface area of a cube is 2 (L²+L²+L²)

    =2 (3L²)

    = 6L²

    Where L is the length of the cube

    If the total surface area of a cube is 302.46ft², then

    302.46 = 6L²

    L² = 302.46/6

    L² = 50.41

    L = √50.41

    L = 7.1ft

    The length of the side of the cube is 7.1ft
