HELP, THANKS
The properties of a cube are listed below:
Density = 40 g/cm3
Length of side = 2 cm
What is the mass of the cube?

Respuesta :

The mass of the cube with length of 2cm is [tex]320g[/tex]

  • We were given length of cube as [tex]2cm[/tex]

To know the volume of cube we can use the expression

Volume of cube = [tex]a^{3}[/tex]

Where a= length of cube=[tex]2cm[/tex]

Then volume of the cube [tex]2^{3} = 8 cm.[/tex]

  • Density was given as [tex]( \frac{40g}{ cm^{3} } )[/tex]

But we know that density is the ratio of mass to the volume of a substance.

  • Then[tex]Density= \frac{ mass }{ volume }[/tex]

But we are looking for mass of the object, the we can make Mass as subject of the formula

  • [tex]Mass= density * volume[/tex]

Them substitute the values

  • [tex]Mass = (40 * 8)[/tex]

[tex]= 320g[/tex]

Therefore mass of the cube is [tex]320g[/tex]
