Question

A metal has a density of 8.0g/cm cube a solid cube of mass 1.0kg is made from this metal how long is each side of the cube?​

Answer 1

Given :

A metal has a density of 8.0g/cm cube a solid cube of mass 1.0kg is made from this metal

Density of metal = 8 g/cm

Mass of a cube solid = 1kg

As we know that

Density = Mass × volume

Where density is denoted by D, mass is denoted by M and Volume is denoted by V

And, 1kg = 1000gm

Let's apply formula and solve the question

→ D = M × V

→ 8 = 1000 × V

→ V = 8/1000 cm³

Now we have to find out side of a solid cube. So, volume of a cube is a³ where a is side

→ V = a³

→ 8/1000 = a³

→ a = ³√8/1000

→ a = 2/10

→ a = 0.2 cm

Hence, each side of a cube is 0.2 cm
