Answer:
11.25 yards
Explanation:
The first thing we must do is see what the volume of the tank would be, which due to the measurements they give us would be:
v = height * width * length
We are asked to calculate the length, therefore:
length = v / (width * height)
volume equals 525, width 16 2/3 (16.67) and height 2 4/5 (2.8), replacing:
length = 525 / (16.67 * 2.8)
length = 11.25
Which means that the length is 11.25 yards
