Calculation of Pressure Exerted by the Honey on the Bottom of the Container

To calculate the pressure exerted by the honey on the bottom of the container, we need to use the formula:

Pressure = Force / Area

First, let's find the force exerted by the honey on the bottom of the container. The force can be calculated using the formula:

Force = Weight = Mass * Gravity

The mass of the honey can be calculated by multiplying its volume by its density:

Mass = Volume * Density

Given that the honey occupies two-thirds of the volume of the container and the height of the container is 75 cm, we can calculate the volume of the honey:

Volume of Honey = (2/3) * Volume of Container

The volume of the container can be calculated by multiplying the area of the base by the height:

Volume of Container = Area of Base * Height

Now, let's calculate the force exerted by the honey on the bottom of the container:

Force = Mass * Gravity = (Volume of Honey * Density) * Gravity

Next, we need to calculate the area of the bottom of the container. The area can be calculated using the formula:

Area = Length * Width

Given that the area of the bottom of the container is 0.18 m², we can calculate the length and width of the bottom:

Length * Width = Area of Base

Finally, we can calculate the pressure exerted by the honey on the bottom of the container using the formula:

Pressure = Force / Area

Let's perform the calculations step by step.
