60 g × 0,035274 onz = 2,11644 onz
1 g
V = 2,11644 onz ⇒ 2,3 pul³

d = 1,74 g/ml
h = 1,50 m ⇒ 1,50 m × 100 cm / 1 m = 150 cm
D = 2 cm ⇒ r = D/2 = 2 cm/2 = 1 cm
m= ?
π = 3,1416
d = m ⇒ m = d×v
v
volumen de un cilindro
v = π×h×r²
= 3,1416 × 150 cm × (1cm)²
= 471,24 cm × 1 cm²
v = 471,24 cm³
1 cm³ = 1 ml
v = 471,24 ml
m = d×v
= 1,74 g/ml×471,24 ml
m= 819,96 g
