bantu jawab dong pakai caranyaa....​

Penjelasan dengan langkah-langkah:

7. b

V = Luas alas x tinggi

V = 84 x 17

V = 1.428 cm³

8. a

Lp = (7+12)x6 + (6+7+8+12)x14

Lp = 19x6 + 33x14

Lp = 114 + 462

Lp = 576 cm²

9. b

V = 15x10x8 + 15x10x(20-8)/3

V = 150 x 12

V = 1.800 cm³

10. b

Nilai siswa susulan = (75,2 x 30) - (75 x 29)

= 2.256 - 2.175

= 81
