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
Density = mass/volume = 5.4g/(9*2*6) cm3 = 5.4/108 cm3 = 0.05 g/cm3. Balsa, one of the least dense woods, has a density of 0.16 g/cm3 which is more than 3 times the "density" of your wood! So have you discovered a super-light wood species?
You would use a balance or a scale to find the mass of the block in the laboratory. These instruments provide accurate measurements of mass by comparing the weight of the object with a set of calibrated weights.
To find the density of a block, calculate the block's mass and volume. Then, divide the mass by the volume to get the density. The formula is density = mass/volume.
?????????????????????
To find the density of a block, you can use a balance to measure its mass and a ruler to measure its dimensions. Divide the mass of the block by its volume (calculated from its dimensions) to determine the density.
A graduated cylinder or volumetric flask could be used to measure the displacement of water when the wood block is submerged in it. By measuring the volume of water displaced, you can determine the volume of the wood block. A balance can then be used to measure the mass of the wood block, allowing you to calculate its density.
You would use a scale to measure the mass of a block. Place the block on the scale and record the reading to determine its mass.
To calculate the density of a block, you would need to know its mass and volume. Density is calculated by dividing the mass of the block by its volume: Density = mass/volume. The resulting value will be in units such as grams per cubic centimeter (g/cm3) for solid blocks.
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.

Use the formula Density = Mass/Volume. If you cant plug in the values...then your professor is not doing his job well.
The volume of a block of wood can be calculated by multiplying its length, width, and height. The formula for volume is V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height of the block.
