Calculando o volume:
V= A*h
V= (4 m²)*(3m)
V=12m³
convertendo m³ para L:
1 m³ 1000 L
12 m³ x
x=12*1000
x=12000 L
De L para mL:
1 L 1000 mL
12000L x
x=12000*1000
x=12000000 mL
Convertendo a massa de Kg para g:
1 Kg 1000 g
30000 Kg --- x
x=1000*30000
x=30000000g
d=m/V
d= (30000000g)/(12000000 mL)
d= 0,25 g/mL
