tolong ya kak di jawab no 9 dan 10

9. Volume kubus
v= r3
= 1m3
= 1.000 liter

Volume Balok
v= p×l×t
= 45×20×25
= 22.500cm3
= 22,5 liter
volume air yang dapat dimasukkan=
vkubus - v balok = 1.000 - 22,5 = 977,5 liter

10. cari volume air dulu
= 5/8 × 6 × 4 × 8
= 120 dm3

Cari tinggi air
= v = p × l × t
120 = 6 × 4 × t
120 = 24 × t
t = 120 : 24
t= 5 dm

Good Luck!!!!!
