Penjelasan dengan langkah-langkah:

29.

$v1 = {10}^{3} = 1000 \ v2 = 20 times 10 times 12 = 3600 \ v : bangun = 1000 + 3600 = 4600$

30.

$v1 = frac{1}{3} times 25 times 10 times 15 = 25 times 10 times 5 = 1250 \ v2 = 25 times 10 times 10 = 25 times 100 = 2500 \ v : bangun =1250 + 2500 = 3750$

31.

$v1 = {6}^{3} = 216 \ v2 = 7 times 12 times 9 = 756 \ v : bangun = 216 + 756 = 972$

32.

$v1 = frac{1}{3} times frac{22}{7} times 7 times 7 times 6 = 22 times 2 times 7 = 308 \ v2 = frac{22}{7} times 7 times 7 times 12 = 22 times 7 times 12 = 1848 \ v : bangun = 308 + 1848 = 2156$

33. Banyak kubus kecil = volume kubus utama ÷ volume kubus kecil

=729÷27=27pcs

34.

$frac{22}{7} times 7(7 + (2 times 21)) = 22(7 + 42) = 22 times 49 = 1078$

35. volume ½ bola atas dan bawah sama jadi bisa dihitung dengan rumus 1 bola lalu ditambar volume tabung

$vbola = frac{4}{3} times frac{22}{7} times 7 times 7 times 7 \ = frac{4}{3} times 22 times 49 = 1437.3 \ vtab = frac{22}{7} times 7 times 7 times 20 = 22 times 7 times 20 = 3080 \ vbangun = 1437.3 + 3080 = 4517.3$
