This question clearly states that it is a 'find the volume' question.
Given dimensions of the object are :
Length of the object = 
inches or 40.5 inches
Depth of the object = 10 inches
Height of the object is = 8 inches
So, the volume becomes = 
= 3240 cubic inch
Hence, the amount of cement needed is 3240 cubic inches.
You would take your number, let's use 55, and multiply it by 0.35.
55 x 0.35 = 20.25
Then add that answer to your original number.
55 + 20.25 = 75.25
Your answer is 17.25.
1/3x - 2 = 1/4x + 11....it looks to me like one y was subbed in for another...
ur 2 equations are :
y = 1/3x - 2 and y = 1/4x + 11...but we need them in standard form...
y = 1/3x - 2
-1/3x + y = -2 ..multiply by 3
-x + 3y = -6.....or 3y - x = -6 <==
y = 1/4x + 11
-1/4x + y = 11 ...multiply by 4
-x + 4y = 44 or 4y - x = 44 <==
