5. v = Luas alas x t

1.785 = 105 x t

t = 1.785/105

t = 17

6. volume kubus

v = s x s x s

v = 15 x 15 x 15

v = 3.375

volume balok = 15x kubus jadi 3.375 x 15 = 50.625

7. 56/4 = 14

v = s x s x s

v = 14 x14 x 14

v = 2744

8. ³√1331 = 11

9. ³√216 = 6

10. v = p x l x t

1632 = 17 x 8 x t

1632 = 136 x t

t = 1632/136

t = 12

11 v balok = p x l x t

v balok = 12 x 8 x 18

v balok = 1.728

rusuk kubus = ³√1.728

= 12

12 v kubus = 10 x 10 x 10

= 1.000

v balok = 14 x 10 x ( 7+10 )

v balok = 2.380

v kubus + v balok = 3380

13. v = luas alas x t

1512 = 126 x t

t = 1512/126

t = 12

14. v kubus = s x s xs

v kubus = 10 x 10 x 10

v kubus = 1000

karena v balok 5 kali v kubus jadi

v balok = 1000 x 5 = 5000

15. v = 10 x 10 x 10

v = 1000
