Answer:
The height of the tank is 15 cm
Explanation:
Volume of the tank's base = length × width × height
Volume of the base = 40 cm × 60 cm × h
= 2400h cm³
The base is 1/3 filled with water, so the volume of water in the base = (1/3) × volume of the base.
= (1/3) × 2400h
= 800h cm³
volume needed = 2400h - 800h
= 1600h cm³
volume needed (in liters) = 1600h cm³ / 1000 = 1.6h liters
1.6h liters = 24 liters
1.6h = 24
h = 24 / 1.6
h = 15 cm
Therefore, The height of the tank is 15 cm
