Answer 3

1 gallon [UK] = 0.160 543 653 24 cubic foot

14 000 gallon [UK] = 2 247.611 145 3 cubic foot

38 ft *8 ft * X ft =14000gal

38 ft *8 ft * X ft =2 247.611 145 3

X ft =2 247.611 145 3 cubic foot / 38 ft *8 ft

X ft =2 247.611 145 3 / 38*8

X ft = 7.3934577148026315789473684210526

7.3934577148026315789473684210526 is the value of _ in ft

7.39 ft is the dimension you needed.

Answer 4

38ft x 8ft = 304ft² = 14,000gal.

14,000gal. / 7.5 USgal/ft³ = 1,867ft³.

38 x 8 x H = 1,867

H = 1,867 / 304 = 6.14ft.

(Check: 38 x 8 x 6.14 = 1,867ft³ x 7.5gal/ft³ = 13,999.2 US.gal.

(If Imperial gallons, use 14,000 gal / 6.24gal/ft³ = 2,244 ft³.

H = 2,244 / 304 = 7.4ft).
