Answer:
X = 62.4
Explanation:
To find x or the weight of water per one cubic foot we take the 12.48 and divide it by two
12.48 = 6.24
Then multiply 6.24 by ten because 6.24 is the weight of .1 cubic feet
6.24 * 10 = 62.4
To check and make sure we calculated it correctly we can do 6.24 * 17 to find the weight of the larger tank
6.24 * 17 = 106.08
And 6.24 * 15 to find the weight of the smaller tank
6.24 * 15 = 93.6
The subtract 93.6 from 106.08
106.08 - 93.6 = 12.48 which was the difference in weight between the two tanks.
