Penjelasan dengan langkah-langkah:

1. Volume Gabungan

= V.kubus + V.Balok

= ( s × s × s ) + ( p × l × t)

= ( 8 × 8 × 8)+( 10 × 8 × 4)

= (512)+(320)

= 832 cm³

2. LP Gabungan

= ( LP Balok tanpa tutup)+(Ls.Limas)

= ((la+ls)) + (4 × ls)

= ((16×16)+(4×16×4)) + ( 4 × ½ × 16 × 8)

= (256+256)+(256)

= 768 cm²

3. LP Gabungan

= (LP Tabung tanpa tutup)+(Ls.Kerucut)

= (πr²+(πdt)) + (πrs)

= ((22/7 × 7 × 7)+(22/7 × 14 × 10)) + (22/7 × 7 × 11 )

= ((154+440)+(242)

= 736 cm²

4. Volume Gabungan

= V.Tabung + V.Kerucut

= (πr²t)+(⅓πr²t)

= (3,14 × 5 × 5 × 4 ) + (⅓ × 3,14 × 5 × 5 × 6)

= ( 314) + (157)

= 471 cm³

5. Volume Gabungan

= V.½Bola + V.kerucut

= (4/3½πr³) + (⅓πr²t)

= (4/3 × ½ × 3,14 × 9 × 9 × 9)+(⅓ × 3,14 × 9 × 9 × 11)

= 1526,04 + 932,58

= 2458,62 cm³
