Answer:
It's C: 400
Explanation:
The inside dimensions of the tank are:
h = 40 inches
w = 40 inches
l = 48 inches
Convert to Feet:
h = 40 inches / 12 = 3.33 feet
w = 40 inches / 12 = 3.33 feet
l = 48 inches / 12 = 4 feet
Volume of one tank = 3.33 feet * 3.33 feet * 4 feet
= 44 cubic feet (approximately)
Since there are nine tanks, we multiply the volume of one tank by nine to get the total volume:
Total volume = 44 cubic feet * 9
= 396 cubic feet
Rounding the answer to the nearest whole number, the total volume is approximately 396 cubic feet.
Therefore, the correct answer among the given options is 400.
Hope that helped!
