Jawab:
v=10.500cm³
Penjelasan dengan langkah-langkah:
V balok=p×l×t
=35 cm×20 cm×15 cm
=700cm²×15cm
=10.500cm³
jadi volumenya adalah 10.500cm
Luas permukaan balok:
2 × ( p × l ) + ( l × t ) + ( p × t )
Lp = 2 × ( p × l ) + ( l × t ) + ( p × t )
Lp = 2 × ( 35 cm × 20 cm ) + ( 20 cm× 15 cm ) + ( 35 cm × 15 cm)
Lp = 2 × (700 cm + 300 cm + 525 cm)
Lp = 2 × (1.000 cm + 525 cm)
Lp = 2 × 1.525 cm
Lp = 3.050 cm²
Volume balok =
V = p × l × t
V= 35 cm × 20 cm × 15 cm
V = 700 cm × 15 cm
V = 10.500 cm³
Semoga bermanfaat..
