Answer:
the density of copper is 90.03g/cm³
Step-by-step explanation:
This problem bothers on the density of a substance, this case for a copper material
Given data
Mass of copper m = 1355g
Volume of copper block v= l*b*h
10*5*3=150cm³
We know that the density
ρ= mass/volume
ρ= 1355/150
ρ= 90.03g/cm²
The density of a substance is defined as the mass of the substance per unit volume
Answer:
n < 5
Step-by-step explanation:
(3n + 5) + (-5) < 20 + (-5)
3n + 5 - 5 < 20 - 5
3n < 15
3n/3 < 15/3
n < 3*5/3
n < 5
