Answer:
17.3 in
Explanation:
Given the following :
Length of tank = 20 inches
Width of tank = 10 inches
Amount of water poured into tank = 15 gallons
Volume(V) of tank (rectangular prism)
V = Length × width × height
Height = h
1 gallon = 231 inch³
15 gallons = (231 × 15) = 3465 in³
Hence V = 3465 in³
3465in³ = 20 in × 10 in × h
3465 in³ = 200h
h = 3465 / 200
h = 17.325 in
Height = 17.3 in ( nearest tenth)
