    answer

    567000 J

    formula

    the formula for power is P = ΔE/Δt

    rearrange for energy to get ΔE = PΔt

    P is power in watts (W)

    E is energy in joules (J)

    t is time in seconds (s)

    values

    P = 315 W

    t = 30 minutes = 30 * 60 = 1800 s

    plug in values

    ΔE = PΔt

    ΔE = 315 * 1800

    ΔE = 567000 J
