  • 27 = Lp kubus = 6 x s x s
    = 6 x 15 x 15 = 1350 D


    28 = v tabung = 22/7 x r x r x t
    = 22/7 x 7 x 7 x 30 = A 4620


    29 = v 1 = 22/7 x r x r x t
    = 22/7 x 7 x 7 x 20 = 3080

    v 2 = P x L x T = 20 x 18 x 8 = 2880

    volume gabungan = 3080 + 2880 = 5960





    dicek lagi yh. takut ada yg salah
