27. volume balok = p x l x t = 160 x 80 x 50 = 640.000 cm³
sudah diisi 1/4 = 640.000 x 1/4 = 160.000 cm³
yang belum diisi = 640.000 - 160.000 = 480.000 cm³ (C)

28. volume prisma = luas alas x t = 16 x 12 /2 x 32 = 16 x 6 x 32 = 3.072 cm³ (C)

29. volume tabung = luas alas x t = phi x r x r x 28 = 22/7 x 9 x 9 x 28
                                                                                    = 22 x 81 x 4 = 7.128 cm³ (C)

semoga membantu ^-^
