Jawab:
no 8: 1.583 cm³
no 10: 7.832 cm³
Penjelasan dengan langkah-langkah:
no 8. (gambar kubus dan balok)
Volume kubus = S x S x S = 5 x 5 x 5 = 125 cm³
Volume balok = P x L x T = ( 14 - 5 ) x 18 x 9 = 9 x 18 x 9 =1.458 cm³
Vkubus + Vbalok = 125 + 1.548 = 1.583 cm³
no 9. maaf sy blm bljr yg itu hehe
no 10. (gambar kerucut dan tabung)
r = d : 2 = 7cm t = 18cm
Volume kerucut = 1/3 x
