The kerosene tank has a length of 40 cm, a width of 25 cm, a height of 60 cm
The kerosene tank has a length of 40 cm, a width of 25 cm, a height of 60 cm, determine the mass of kerosene if the tank is half full. p = 800kg / m3.
First, let’s find the volume of the tank:
V = a * b * c, where a, b and c are the length, height and width of the tank.
V = 0.4 * 0.25 * 0.6 = 0.06 m ^ 3.
According to the conditions of the problem, the tank is filled with kerosene only up to half, that is, the volume of kerosene is Vк = V / 2 = 0.06 / 2 = 0.03 m ^ 3.
Next, we find the mass of kerosene by the formula: m = p * Vk, where m is the mass (kg), p is the density of kerosene (kg / m ^ 3 – 800 kg / m ^ 3 according to the condition of the problem), Vk is the volume occupied by kerosene ( m ^ 3).
m = 800 * 0.03 = 24 kg.
Answer: the mass of kerosene is 24 kg.
