Answer:
I think its C but if its not try A then
Explanation:
Answer:
V = 4480.56 cm3
Explanation:
Data Given
Length “l” = 14 inches
Hight “h” = 7 inches
Width “w” = 1.5 feet
Volume= “V”
Solution:
Formula to Use
V= l . w. h
Note: here we have to values in the same unit
So the Length “l” and Hight “h” both are in inches but the width is in feet
So we changes the feet into inches
1 foot = 12 inches
1.5 feet = 12 x 1.5
1.5 feet = 18 inches
So width is 18 inches
Now putting the values in formula
V = l . w. h
V = 14 . 18 . 7
V = 1764 inch
You can convert inches to cm
1 inch = 2.54 cm
So 1764 inches = 2.54 x 1764
1764 inches = 4480.56 cm3
So
V = 4480.56 cm3

Answer:
(i) 5-day BOD of the waste is 120 mg/l.
(ii) The ultimate carbonaceous BOD (Lo) is 20 mg/l.
Explanation:
The dilution factor D is 0.05.
The initial DO is 8.0 mg/L and the DO after 5 days is 2.0 mg/L.
The BOD of the waste for an unseeded mixture is

The ultimate carbonaceous BOD (Lo) can be calculated as
