Answer: 108 cm squared
Step-by-step explanation: To find the lateral area, you have to multiply the perimeter of the base by the height of the rectangular prism.
1. Perimeter: 10 + 10 + 8 + 8 = 36
2. Lateral area: 36 * 3 = 108

Assume that solution with 20% and 50% salt is x and y gallons respectively.
Therefore,
x+y = 300 => y=300-x
Additionally
20x+50y = 300*41 = 12300
Substituting for y
20x+50(300-x) = 12300 => 20x+15000-50x = 123000 => -30x = -2700
x= 90 gallons
y= 300-x = 300 - 90 =210 gallons
(Sqrt 87)/16

We are given with a company profit of $ 5 profit where 2% of the products are faulty and the replacement-and-repait costs for the fauly products are equivalent to $ 100 each. Due to these faulty products, the equation becomes $ 5/ 1 = $ x / 0.98. The proft per item then is $ 4.9.
