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.

Answer:
150 miles
Step-by-step explanation:
let m represent miles
$70 + .70m = $40 + .90m
subtract 40 from each side
$30 + .70m = .90m
subtract .70m from each side
$30 = .20m
divide both sides by .20
150 = m
