Tolong jawab yg bnr bsk d kmpln

27.15*12*8 = 1440
28. 16*12/2 *28 = 2688
Semoga berguna

27) V = p x l x t = 15 . 12 . 8 = 180 . 8 = 1440 cm³

28) V = (a x t segitiga x 1/2) x t prisma = (16 x 12 x ½) x 28 = 8 . 12 . 28 = 96 . 28 = 2.688 cm³

29) 22/7 . r² x t = 22/7 . 7 . 7 . 30 = 22 . 7 . 30 = 154 . 30 = 4620 cm³

kalau salah maaf ya…
