    Answer:

    2197 cm³

    Step-by-step explanation:

    To start with, I’d just the formulas needed

    Total Surface Area of a cuboid, A =

    A = 2lw + 2lh + 2hw, where,

    l = length of the cuboid, 33 cm

    h = bright of the cuboid, 9 cm

    w = width of the cuboid, 5 cm

    A = 2(33 * 5) + 2(33 *9) + 2(9 * 5)

    A = 2(165) + 2(297) + 2(45)

    A = 330 + 594 + 90

    A = 1014 cm²

    If the total surface area of the cuboid is 1014 cm², which were told is also the total surface are of the cube.

    Total surface area of a cube =

    A = 6a², where

    a = the side of the cuve

    A = 6a² = 1014 cm²

    6a² = 1014

    a² = 1014 / 6

    a² = 169

    a = √169

    a = 13

    The formula for volume of cube is

    v = a³

    V = 13³

    V = 2197 cm³
