What is the density of lead if a cube measuring 2 cm per side has a mass of 90.8 g?

Answer:

8.1 g/cm

3

Explanation:

Density is equal to mass divided by volume. You are given a mass of  

64.7

grams. You can find the volume of the cube by doing height multiplied by width multiplied by depth.

Because all of the sides of a cube are the same length, the volume just ends up being  

2

3

.

(

2 cm

)

3

=

8 cm

3

Now plug both of those numbers into your density equation

ρ

=

m

V

=

64.7 g

8 cm

3

=

8.1 g/cm

3

Step-by-step explanation:

Answer:

8,1 g / cm

3

Explicación:

La densidad es igual a la masa dividida por el volumen. Se le da una masa de  

64,7

gramos. Puede encontrar el volumen del cubo multiplicando la altura por el ancho por la profundidad.

Como todos los lados de un cubo tienen la misma longitud, el volumen acaba siendo  

2
