Jawaban:
2. 128 cm³
3. 285 cm³
4. 374 cm³
5. 480 cm³
Penjelasan dengan langkah-langkah:
v gab = v balok atas + v balok bawah
= ( p × l × t ) + ( p × l × t )
= ( 8 × 4 × 2 ) + ( 4 × 2 × 8 )
= 64 + 64
= 128 cm³
v gab = v balok + v kubus
= ( p × l × t ) + ( s × s × s )
= ( 4 × 5 × 8 ) + ( 5 × 5 × 5 )
= 160 + 125
= 285 cm³
v gab = v balok kiri + v balok kanan
= ( 5 × 5 × 11 ) + ( 3 × 3 × 11 )
= 275 + 99
= 374 cm³
v gab = v prisma segitiga + v balok
= ( 1/2 × p × l × t ) + ( p × l × t )
= ( 1/2 × 10 × 6 × 4 ) + ( 10 × 6 × 6 )
= ( 5 × 6 × 4 ) + ( 10 × 6 × 6 )
= 120 + 360
= 480 cm³
