<h2>Answer:</h2>
The unit of density is:
Kilograms per cubic centimeter.
<h2>Step-by-step explanation:</h2>We know that the density of a substance is defined as the ratio of the mass of a substance to it's volume.
i.e.
Now, we know that the standard unit of the mass of a substance is: Kilograms(kg)
and the standard unit for a volume is: cubic centimeters(cm³)
Hence, we will get the unit for density as:
Kilograms per cubic centimeter

Answer: 60
Step-by-step explanation:
Let the side lengths of the rectangular pan be m and n. It follows that (m-2) (n-2)=
So, since haf of the brownie pieces are in the interior. This gives 2 (m-2) (n-2) =mn
mn- 2m - 2n- 4 = 0
Then Adding 8 to both sides and applying, we obtain (m-2) (n-2) =8
Since now, m and n are both positive, we obtain (m,n) = (5,12), (6,8) (up to ordering). By inspection, 5. 12 = 60
which maximizes the number of brownies in total which is the greatest number.
Hope that helped! =)
