Question

The approximate densities of four metals in g/cm are given below:
Aluminium 2.9 g/cm
Brass 8.8 g/cm
Copper 9.3 g/cm3
Steel 8.2 g/cm

A cube of an unknown metal has side lengths of 5 cm. The mass of the cube is 1.1 kg.
a) By calculating the cube's density, determine which metal the cube is likely to be made from.
Another cube made of steel has a mass of 4.0kg.
b) Calculate the length of each of the sides of the steel cube, giving your answer to 1 d.p​

Answer 1

Answer:

I don't know answer for this questions

Answer 2

Answer:

For sub questions :

A) Brass

A) Brass B) Volume = 454.545 cm^3

Step-by-step explanation:

FIRSTLY :

Volume = 5 cm * 5cm * 5 cm = 125 cm^3

Mass = 1.1 kg = 1100 g

SO :

Density = 1100/125 = 8.8 g/cm^3

[ now that you have found density , you can put the value in sub questions A and B ]

A) Brass will will be the metal which will most likely make the cube since it has a density of 8.8g/cm^3

B) Given :

Mass = 4.0 kg = 4000g

Density = 8.8g/cm^3

Volume = Mass/ Density

so Volume = 4000/8.8

= 454.545 cm^3
