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:
-2/3
Step-by-step explanation:
-2/3= -.066666667
-3/5= -0.6
3/10= 0.3
11/20= 0.55
Two because if there was seven and i take five it gives you two
