tolong ya jawab nomor 7 sampai 11

7.) volume = p × t × l
10 × 2 ×4 = 80
8.) Volume = p × t × l
15 × 8 × 12 = 120 × 12 = 1440
9.) Tinggi = t/p = 2500/100 = 25/ lebar = 25/5 = 5. Jadi tinggi = 5
10.) Volume = 3/4 × p × t × l
3/4 × 70 × 60 × 50
3/4 × 210.000 = 630.000/4 = 157.500 cm3 = 157,5 liter
11.) volume = p × l × t
15 × 12 × 10 = 1.800
1.800 × 3/5 = 1.080 liter
