Explicación:
La densidad se expresa como masa por unidad de volumen de un objeto.
Densidad = masa / volumen
1) Densidad dada = 0.92g / cm³, volumen = 1 litro = 1000cm³
Masa del aceite = Densidad del aceite * volumen del aceite
Masa del aceite = 0,92 * 1000
masa del aceite = 920 gramos
2) Volumen del prisma = Área base * Altura
V = LBH
Longitud dada = 3 cm, ancho = 0.5dm = 5 cm y altura = 20 mm = 2 cm
Volumen del prisma = 3 * 5 * 2 = 30 cm³
Densidad del cobre = 9g / cm³
Masa = Densidad * volumen = 30 * 9
masa del cobre = 270 gramos
3) Dada masa de mercurio = 1 kg = 1000 g
Densidad de mercurio = 13.6g / cm³
Volumen = Masa / Densidad
Volumen del cobre = 1000 / 13.6
Volumen del cobre = 73.53cm³
