    The weight of the body, W = 793.8 m/s²

    Explanation:

    Given,

    The volume of the body, v = 45,000 cm³

    The density of the body, ρ = 1.8 g/cm³

    The mass of the body is given by the formula,

    m = ρ x v

    = 1.8 g/cm³ x 45,000 cm³

    = 81,000 g

    Hence, the mass of the body is m = 81 kg

    The weight of the body,

    W = m x g

    = 81 kg x 9.8 m/s²

    = 793.8 m/s²

    Hence, the weight of the body, W = 793.8 m/s²
