13. V = 22/7 x 14 x 14 x 20 + 28 x 28 x 20 = 12320 + 15680 = 28000 cm3 14. V= 22/7 x 5 x 5 x7 + 22/7 x 10 x 10 x 14 = 550 + 4400 = 4950 cm3 15. V = 5x6x7 + 22/7 x 1,75 x 1,75 x 3 = 210 + 28,875 = 238,875 dm3 atau 238875 cm3
= 12320 + 15680
= 28000 cm3
14. V= 22/7 x 5 x 5 x7 + 22/7 x 10 x 10 x 14
= 550 + 4400
= 4950 cm3
15. V = 5x6x7 + 22/7 x 1,75 x 1,75 x 3
= 210 + 28,875
= 238,875 dm3 atau 238875 cm3
