Jawaban:
19. c. 8 cm
20. c. 17 cm
22. d. 12 dm
Penjelasan dengan langkah-langkah:
19. V = p × l × t
1.680 = 21 × 10 × t
1.680 = 210
t = 1.680/210
t = 8 cm
20. V = p × l × t
12.920 = p × 38 × 20
12.920 = p × 760
p = 12.920/760
p = 17 cm
22. V = p × l × t
1.800 = 15 × 10 × t
1.800 = 150 × t
t = 1.800/150
t = 12 dm
