An oil tank measures 3m long, 3m wide, and 2m high, filled with coconut oil of specific gravity 0.90. What is the downward force at the bottom of the tank?

To determine the downward force at the bottom of the oil tank filled with coconut oil, we need to calculate the weight of the oil and convert it into a force measurement.

First, we find the volume of the tank, which is calculated by multiplying its length, width, and height. In this case:

Volume = Length × Width × Height

Volume = 3m × 3m × 2m = 18 cubic meters (m³).

Next, we need to find the weight of the coconut oil in the tank. To find the weight, we first calculate the mass using the specific gravity and the fact that the specific gravity is the ratio of the density of the substance to the density of water (which is approximately 1000 kg/m³). Since the specific gravity of coconut oil is 0.90:

Density of coconut oil = Specific gravity × Density of water

Density of coconut oil = 0.90 × 1000 kg/m³ = 900 kg/m³.

Now, we can calculate the mass of the coconut oil in the tank by multiplying the density by the volume:

Mass = Density × Volume

Mass = 900 kg/m³ × 18 m³ = 16,200 kg.
