Answer:
The answer is
<h2>376 cm²</h2>
Step-by-step explanation:
Since the rectangular box is a cuboid,
Total surface area of a cuboid is given by
<h3>2( lw + wh + lh)</h3>
Where
l is the length
w is the width
h is the height
From the question
l = 10 cm
w = 8cm
h = 6cm
Substitute the values into the above formula
That's
Total surface area of the rectangular box is
2 [ (10)(8) + (8)(6) + (10)(6) ]
2 [ 80 + 48 + 60 ]
2( 188)
We have the final answer as
<h3>Total surface area = 376 cm²</h3>

Answer:
-11
Step-by-step explanation:
The given expression is:
![|-4b-8|+|-1-b^2|+2b^3](https://tex.z-dn.net/?f=%7C-4b-8%7C%2B%7C-1-b%5E2%7C%2B2b%5E3)
=![|-(4b+8)|+|-(1+b^2)|+2b^3](https://tex.z-dn.net/?f=%7C-%284b%2B8%29%7C%2B%7C-%281%2Bb%5E2%29%7C%2B2b%5E3)
=![4b+8+1+b^2+2b^3](https://tex.z-dn.net/?f=4b%2B8%2B1%2Bb%5E2%2B2b%5E3)
=![4b+9+b^2+2b^3](https://tex.z-dn.net/?f=4b%2B9%2Bb%5E2%2B2b%5E3)
Substituting the value of b=-2 in above expression, we get
=![4(-2)+9+(-2)^2+2(-2)^3](https://tex.z-dn.net/?f=4%28-2%29%2B9%2B%28-2%29%5E2%2B2%28-2%29%5E3)
=![-8+9+4-16](https://tex.z-dn.net/?f=-8%2B9%2B4-16)
=![-11](https://tex.z-dn.net/?f=-11)
Thus, the value of the given expression is -11.
Just find the unit price (price divided by amount)
6 lb for $50.00
50.00/6 = about $8.33 per lb
6.5 lb for $60.00
60.00/6.5 = about $9.23 per lb
<em>6 lb for $50.00 would be the better deal</em>
