The surface area of a shape is the amount of space on the shape
When the dimensions are quadrupled, the new surface area would be 16 times the initial surface area
<h3>How to determine the surface area</h3>
The surface area of a rectangular prism is:
![S = 2 * (lw + lh + wh)](https://tex.z-dn.net/?f=S%20%3D%202%20%2A%20%28lw%20%2B%20lh%20%2B%20wh%29)
When quadrupled, we have:
![S_2 = 2 * (16lw + 16lh + 16wh)](https://tex.z-dn.net/?f=S_2%20%3D%202%20%2A%20%2816lw%20%2B%2016lh%20%2B%2016wh%29)
Factor out 16
![S_2 =16 * 2 * (lw + lh + wh)](https://tex.z-dn.net/?f=S_2%20%3D16%20%2A%202%20%2A%20%28lw%20%2B%20lh%20%2B%20wh%29)
Substitute ![S = 2 * (lw + lh + wh)](https://tex.z-dn.net/?f=S%20%3D%202%20%2A%20%28lw%20%2B%20lh%20%2B%20wh%29)
![S_2 =16 * 2 * S](https://tex.z-dn.net/?f=S_2%20%3D16%20%2A%202%20%2A%20S)
The above means that:
The new surface area would be 16 times the initial surface area

$41.04 you multiply how long and how wide it is together. after that that the answer is 2,070 then divide it by 50 and you get $41.04.
i hope that helps!!
1.The temperature will be, T2= 169.8 K
2. The volume if the temperature is 318 K is 0.170 L
<h3>What is Charles Law?</h3>
Charles's law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
Given: V1= 250 ml=0.25L
V2=150 ml= 0.15 L
T1= 10 °C=283 K, T2=?
Now using Charles law
V1/T1=V2/T2
0.25/283=0.15/T2
T2= 169.8 K
2. T1= 20 °C= 293 K
V1= 160 cm³
T2= 318 K
V2=?
Using Charles Law,
V1/T1=V2/T2
0.16/293=V2/313
0.170 L=V2
