Jawaban:
7. 256 buah kubus
8. 20.550 cm³
Penjelasan dengan langkah-langkah:
7. V kubus = S³
4 x 4 x 4 = 64 buah kubus
64 buah kubus x 4 kubus besar = 256 buah
8. V balok = P x L x T
Balok 1 = 30 x 15 x 20
= 9.000 cm³
Balok 2 = (55 - 20) x 15 x 22
= 35 x 15 x 22
= 11.550 cm³
Vol gabungan = B1 + B2
= 9.000 + 11.550
= 20.550 cm³
