What does a 4inches x 8inches x 16inches hollow concrete block weigh?
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.
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 use dreidel in a sentence?
Example sentence - My grandfather taught me how to carve a dreidel from a block of wood.
The mass of a wood block is 33.3 grams It has a volume of 6.02cm What is the Density?
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
What is the density of a block of wood measuring 9cmX2cmX6cm with a mass of 5.4g?
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?
Instrument you would use in the laboratory to find the mass of the block?
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.
How do you find the density of a block?
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.
What is the use of block of wood?
?????????????????????
What tools do you use to find the density of a block?
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.
What laboratory instruments would be most appropriate to use in determining the volume of a large block of wood of unknown 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.
What would you use to measure the mass of a block?
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.
How do you calculate if a block of wood will float in water or not?
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.
How do you get a density of a block?
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.

What is the density of a block of wood if the mass is 6.9 g and the volume is 2.4 cm3?
Use the formula Density = Mass/Volume. If you cant plug in the values...then your professor is not doing his job well.
What is the volume of a block of wood?
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.
