Density of wood = mass/volume
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
Density = Mass/VOlume = 120g/200cm3 = 0.6 grams per cm3
This density is 0,8 g/cm3.
The volume should be 200 cm3, not cm2. Density = Mass/Volume = 120g /200 cm3 = 0.6 g/cm3
To find the mass of a block of wood you should use a triple beam balance.
Density = Mass/Volume
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.
volume,weight and mass
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
Density = Mass/VOlume = 120g/200cm3 = 0.6 grams per 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
density is the product of mass and volume so its density will b 100 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.
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.
volume of block is l*b*h/mass i.e 3*4*h/37 (g/cc)
density = mass ÷ volume = 600 g ÷ 30 cm3 = 20 g/cm3
