To find the mass of a block of wood you should use a triple beam balance.
you need to have the density of the concrete block. after you find it, use the formula density = mass/volume --> mass = density x volume to calculate the mass. if you want to find the weight in Newtons, use W = mg where m is the mass and g is 9.81N/kg. that will give you the weight of the block. for this case, the volume is 4m x 8m x 16m ( i assume it is in metres cos no units were given) = 512m^3. find the density in kg/m^3 and use the above formula mass = density x volume to calculate the mass. use W = mg to find the weight of the block in Newtons.
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.
What do you use to find mass
Example sentence - My grandfather taught me how to carve a dreidel from a block of wood.
Centimeters are not the right units to use for volume. Although, if it is centimeters cubed(cm^3) then it would be: 33.3g / 6.02cm^3 = 5.53156 g/cm^3
You will need the mass and volume of the block. To find mass, use an electronic balance. To find volume, use length x breadth x height. For irregular solid, use the water displacement method. The density is mass divided by volume.
?????????????????????
If the density of the block is less than the density of water, then the block will float. Density of water is close to 1 gram per cubic centimeter. So measure the block and calculate its volume (Length x Width x Height). Use a scale to find the block's mass. Then divide mass/volume to calculate density. If you've measured in grams and centimeters, then the units will be g/cm³, then compare this to 1 g/cm³.

IF you knew the volume of the block and the density of the material it was made of you could calculate it mass (mass = density * volume) but it is normal to measure the mass of something using a mass balance.
Use the formula Density = Mass/Volume. If you cant plug in the values...then your professor is not doing his job well.

it is easy. You use Mass divided by Volume. You can Remember it by a heart. The top is a M and the bottom is a V. Mass divided by volume. <3
The Density of aluminium is always 2.7g/cm3. To find the density you have to calculate the mass, lenght, breadth and height. Afterwards you have to find the volume (lxbxh).After you find the volume you have to use the formula: = mass/volume.density
What do you use to find mass
A balance.
I am not use why the block of wood would move with the table cloth. It could be because you do not have to wood tied to the table.
