A tank with dimensions of 2 * 4 * 3 m must be memorized halfway with water.

A tank with dimensions of 2 * 4 * 3 m must be memorized halfway with water. To fill the tank, use a vessel with a volume of 0.5 liters. How many times you need to use a vessel for this.

These tasks: dimensions of the tank filled with water 2x3x4 m; Vc (volume of the vessel for filling the tank) = 0.5 l; the tank should be half full.

1) The total volume of the tank: V = a * b * c = 2 * 3 * 4 = 24 m3.

2) Part of the tank volume that needs to be filled with water: V1 = V / 2 = 24/2 = 12 m3 (12 * 10 ^ 3 l).

3) The number of uses of the vessel to fill the tank: n = V1 / Vc = 12 * 10 ^ 3 / 0.5 = 24,000 rubles.

Answer: To fill half of the tank with water, you need to use the vessel 24,000 times.
