The units for density are incorrect. If the density of a block of wood is 0.5 g/cm3 then the volume of a 27 g block would be 27/0.5 cm3 = 54 cm3

since D=m/v... then the density of the block of wood would be mass / volume..... mass in grams divided by volume in ml.



Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.


Density = mass/volume = 100/50 = 2gm/ccThere is no real wood in the real world with that great a density.There are lead sinkers inside your block of wood.


density is the product of mass and volume so its density will b 100 g/cm3..


you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume



The density is 2,01 g/cm3 because the density is ratio between the mass and volume.




density has a formula: density=Mass/Volume. put mass and volume into the equation you have your answer. note:the values are not in metres and KG. they are in grams and cm. convert hem before you work it out.




Density= Volume/Mass. Therefore: (9x2x6)divided by 5.4g=Density. 108cm/5.4g=Density. 20=Density.



Use the formula Density = Mass/Volume. If you cant plug in the values...then your professor is not doing his job well.


1g/cm3Method:The volume of the wood is 3cm x 3cm x3cm, or 27cm3The mass is 27g.Density = mass/volumeTherefore, the density is 27/27, or 1g/cm3


u need the volume . if u did have the volume u would divide the mass (27g) by the volume. then add the label g/ml


Volume cannot be measured in centimetres and so the question makes no sense.


The volume should be 200 cm3, not cm2. Density = Mass/Volume = 120g /200 cm3 = 0.6 g/cm3


Density = mass/volume The volume of the block of wood is 9 cm X 2 cm X 6 cm = 108 cm3. The density of the block of wood is 5.6 g/108 cm3 = 0.05 g/cm3. This is probably a superlight balsa wood.


Density means mass per unit volume. Hence, mass of a body divided by it's volume will give us it's density. Here mass = 4g, volume= 5cm3 So, density = mass/volume =4g/5cm3 =0.8g/cm3 This is the average density of the wooden block. The density of block whole throughout it's body may not always be equal to this value. Some portions of block can be more dense and some less dense. But the average density of any body having mass= 4g and volume = 5cm3 is always 0.8g/cm3 .


The equation for the density of an object with known mass m and volume V is D=m/V.You are given the mass to be 750g.To figure out the volume of the block of wood, simply multipy all of the dimensions. The volume of a right prism (e.g. a block of wood) is V=length*width*height, so the volume for the block of wood is 12cm*8cm*9cm=864cm3.Now you know both your mass and your volume, so you can calculate the density:D=m/VD=(750g) / (864cm3)D is roughly equal to 0.86806g/cm3.
