Volume of Cuboid = l x b x h
9000 mL = 30 x 15 x h
h = 9000/30 x 15
h = 20cm
The required simplified value of B - A = -6.
<h3>What is simplification?</h3>
The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Since, line Ax + By = 3 and x + 3y = -5 are parallel than slope of both the line will be same,
m = -1/3 = -A/B
From above
A = B/3 - - - - -(1)
Now line Ax + By = 3 passed through the point (-7, 2). So,
-7A + 2B = 3
from equation 1
-7B/3 + 2B = 3
-B/3 = 3
B = -9
Now put B in equation 1
A = -9 / 3
A = -3
Here,
B - A = -9 + 3 = -6
Thus, the required simplified value of B - A = -6.

Idk but it can't be 10 or 9.7 bc a triangle's hypotenuse is always longer than its legs
10 to 11 = 1 hr
11 to 12 = 1 hr
12 to 1 = 1 hr
total = 3 hours
