5. 2.400 m³

6. 192 ton

7. 08.45

Penjelasan dengan langkah-langkah:

5. skala = 1 : 200

1 cm = 200 cm

= 2 m

p = 5 cm = 5 x 2m = 10 m

l = 3 cm = 3 x 2 m = 6 m

t = 2 cm = 2 x 2 m = 4 cm

V = p x l x t

= 10 x 60 x 4

= 2.400 m³

6. skala = 1 : 10.000

1 cm = 10.000 cm

= 100 m

p = 6 cm = 6 x 100 m = 600 m

l = 4 cm = 4 x 100 m = 400 m

L = p x l

= 600 x 400

= 240.000 m²

= 24 Ha

Hasil seluruhnya

24 x 8 ton = 192 ton

7. skala= 1 : 8.000.000

1 cm = 8.000.000 cm

= 80 km

jarak = 2,5 cm = 2,5 x 80 km = 200 km

kecepatan = 80 km/jam

waktu = jarak/kecepatan

= 200/80

= 2,5 jam

= 02.30

sampai tujuan

05.30 + 02.30 + 00.45 = 08.45
