Answer:

573440 kg

Step-by-step explanation:

Given,

Density of copper ( D ) = 8960 kg / m³

Length of cube ( l ) = 4 meters

To find : Mass of solid cube of copper ( m )

Formula : -

Volume of cube = l³

Volume of cube

= l³

= 4³

= 4 x 4 x 4

= 64 meter³

So,

V = 64 meter³

Formula : -

D = m / V

m = D x V

= 8960 x 64

m = 573440 kg

Hence,

The mass of a solid cube of copper is <u>573440</u> kg.
