bantuin dong besok mau di kumpulin no 27 sampai 31 pakai cara ya

27. Lp = (2×25×25) + (2×25×13) + (2×25×13)
= 1250 + 650 + 650
= 2550

28. Volume = 1,5³ = 3,375m³ = 3375 liter
= 1/3 × 3375 = 1125 liter

29. Volume = 3,14 × 6 × 6 × 11,9
= 1346,4

30. Volume = ( 24 × 24 × 24 ) + ( 24× 24 ×48 )
= 13824 + 27648
= 41.472
