    Question

    Find the total surface area of cube whose volume is 64 m³.

    A.

    64 m²

    B.

    96 m²

    C.

    36 m²

    D.

    25 m²

    Correct option is B

    Given:
    Volume of the cube = 64 m³
    Formula Used:
    Volume of a cube = side³
    Total Surface Area (TSA) of a cube = 6 × side²
    Solution:
    Volume of the cube = 64 m³
    side³ = 64
    => side = ∛64 = 4 m
    Now,
    TSA = 6 × side²
    = 6 × 4²
    = 6 × 16
    = 96 m²
