Question

Tolong pake cara semua

Answer 1

31. v kubus = s×s×s = 74.088cm³
s =

= 42 cm

32. 1 kodi = 20 buah
10×20 = 200
kancing 6/kemeja
6× 200 = 1200

33. L seluruh = 1,6 × 2 = 3,2 m²
L kolam = 1 × 0,7= 0,7 m²
3,2-0,7 = 2,5 m²

34. LP = 6×s²
karena tanpa tutup mjd 5× s²
== 5 × (40)²
== 5 × 1600
== 8000cm²

35. rata rata
(13.1)+(14.3)+(15.7)+(16.9)+(17.4)
13 + 42 + 105 + 144 + 68

= 15,5
jd banyak siswa diatas rata rata 9+4 = 13
