The question asks for the height of the water level, not a volume.
V = 2 * 3 * 4
V = 24 cubic feet
20/24 = 5/6 full
V = 2 * 3 * 4
V = 24 cubic feet
20/24 = 5/6 full

assuming the tank was empty,
let the height of the water level be h ft
(2)(3)(h) = 20
h = 20/6 = 3 1/3 ft or
3 ft, 4 inches or appr 3.33 ft
As Ms Sue pointed out, the whole tank only holds 24 ft^3
how can you possible think that 480 ft^3 could be a reasonable answer ??
