Jawaban:

[tex]volume \: balok = p \: \times \: l \: \times t = 70 \times 20 \times 30 = 42.000 \: {cm}^{3} [/tex]

[tex]volume \: prisma = l. \: alas \: \times \: t = ( \frac{1}{2} \times 20 \times 30) \times 50 = 300 \times 50 = 15.000 \: {cm}^{3} [/tex]

Jadi luas bangun gabungan= 42.000+15.000= 57.000 cm^3 (A)

Semoga membantu
