Jawaban:
11. 45.000 cm^3
12. a. 125 cm^3 dan 100 cm^2
12. b. 5 : 4
Penjelasan dengan langkah-langkah:
11. Volume = 3 x (25 cm x 40 cm x 15 cm)
Volume = 45.000 cm^3
12a. Volume Kubus = s x s x s
Volume Kubus = 5 x 5 x 5 = 125 cm^3
Volume Balok = p x l x t
Volume Balok = 10 cm x 5 cm x 2 cm = 100 cm^3
12b. Volume Kubus : Volume Balok
= 125 : 100
= 5 : 4
