What is the density of A rectangular wooden block that measures 10 cm by 4 cm by 2 cm when placed in water and it is floating horizontally with its bottom face 1 point 65 cm below the surface?

It is 0.825g/cm^3. Use the area of the wood to find the area of the water displaced with a depth of 1.65. This will give you the volume of the water and multiply that by it's density(1000kg/m^3) to reveal the mass of the water. The mass of the water should be equal to the mass of the wood. Divide this mass by the volume of the wood(not the water segment), which will give you the density of the wood block. Be careful with the unit conversions, you may do the right math, but still have the wrong answer.

How do you calculate density of a rectangular solid?
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
How do i find the density of a rectangular prism?
You divide its mass by its volume.
What is the density of a rectangular block?
It is the mass of the block divided by its volume.

What influence will the size of the surface and the mass of a floating object have on the floating ability of the object?
The density is important; for floating an object must have a density under the water density (1 g/cm3).
Will the liquid on the top have the highest or lowest density?
The floating liquid will have a lower density than the liquid it is floating on.
Will the liquid on the top have the highest or the lowest density?
The floating liquid will have a lower density than the liquid it is floating on.
If an unkown rectangular substance measures 3.6 cm high 4.21 cm long and 1.12 cm wide and the mass is 21.3g. what is the density?
1.3g/mL
If a substance is floating does it have more or less mass?
mass of a substance is constant at any place in the universe.the reason for floating is its density is less than density of medium in which it is floating
Density measures how?
density= mass/volumedensity
How do you calculate density of a rectangular solid?

Does the water density affect floating?
Yes, water density will affect an object's ability to float.
