Let m be the density of iron
Let M be the density of copper
So, m = M = 101.5 grams
We know that the formula for mass is:
m = d x v
where:
m is mass
d is density
v is volume
the density of iron is calculated by d = m / v, we derived this formula from the mass formula.
So d = 6.8g/ 3.3cm^3 = 2.26 g/cm^3
It was said that the density of iron is more than the density of copper, so 6.8 should be greater than 2xd, it indicates that d is less than 3.4.
Therefore, the density of copper is more likely less than 3.4g/cm^3

Answer:
The surface area is 302 in²
Step-by-step explanation:
Known :
Long (l) = 11 in
Weight (w) = 6 in
Height (h) = 5 in
Asked :
Surface Area (Sa) = ...?
Answer :
Formula :
= 2(l.w) + 2(l.h) + 2(w.h)
= 
= 2 (11×6 + 11×5 + 6×5)
= 2 (66 + 55 + 30)
= 2 × 151
= <u>3</u><u>0</u><u>2</u><u> </u><u>in²</u>
So, the surface area is 302 in²

Answer:
In 286 different ways 10 players can be selected.
Step-by-step explanation:
There are 6 girls and 7 boys in a class. So in total there are 6+7 = 13 number of students in the class.
A team of 10 players is to be selected from the class.
As there is no other conditions are given, we can pick any 10 students from 13 students.
The way we can select 10 players from 13 students is;
= (13 10)
= 13!/10!(13-10)!
= 13!/10! 3!
= (13 × 12 × 11 × 10!)/ 10! 3!
= ( 13 × 12 × 11)/6
= 286
72/9 = 8
