tolong jawab yah soal no 16 sampai 18 makasih pakai cara yah

16. Gambar = Sebenarnya : skala
= 72cm : 8 = A.9cm
17. 200mm-50mm-80mm = C.70mm
18. 4.250L - 1.450L - 1.640L = D.1.160L

16.
72/8 = 9 cm(A)
17.
1 cm = 10 mm
1 dm = 100 mm
SIsa = 20x10 - 0.5 x 100 - 80
= 200 - 50 - 80
Sisa = 70 mm(C)
18.
1 dm kubik = 1 liter
1 m kubik = 1000 liter
Sisa = 4.25 x 1000 - 1450 - 1640
= 4250 - 3090
Sisa = 1160 liter(D)
semoga membantu:)
