Volume:
V = p × l × t
V = 75 cm × 50 cm × 40 cm
V = 3.750 cm × 40 cm
V = 150.000 cm³
V = 150 liter
Luas:
lp = 2 × ( pl + pt + lt )
lp = 2 × (( 75 cm × 50 cm) + (75 cm × 40 cm) + (50 cm × 40 cm)
lp = 2 × (3.750 cm + 3.000 cm + 2.000 cm)
lp = 2 × 8.750 cm
lp = 17.500 cm²
v.balok = p x l x t
= 75cm x 50cm x 40cm
= 150.000 cm³
luas permukaan balok = 2 x (p x l) + (p x t) + (l x t)
= 2 x (75 x 50) + (75 x 40) + (50 x 40)
= 2 x (3.750+3.000+2.000)
= 2 x 8.750
= 17.500 cm²
