1920/50=38.4 liters of deck stain
3.8 liters in a gallon
So approximately 10.1 gallons or 10.14421 gallons of deck stain :)
Answer:
e
Step-by-step explanation:
The answer is B. The values of y must only be positive because it is equal to
The other options states that the values of y could be negative which is why it is wrong.
Hey there!
In this problem, we'll just be finding the surface area of a rectangular prism. In this example, a surface area is a sum of all the areas of each individual face. On this rectangular prism, we have 6 faces, and two of each kind. Our formula is:
SA = 2(lw + wh + lh)
Notice how it has a 2. That two is because those two variables just applies for one side, and there's two for each type of side. On this diagram, the rightmost side's area would be the width (32) times the height (49) and the product would be the area. Let's plug in our numbers:
SA = 2(41 * 32 + 32*49 + 41*49)
Multiply:
SA = 2( 1312 + 1568 + 2009) =
Add:
SA = 2(2880 + 2009)
SA = 2(4889)
SA = 9778 ft squared, or C.
Hope this helps!
