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/V
D=(750g) / (864cm3)
D is roughly equal to 0.86806g/cm3.

A Try Square is used To See if A piece Of Wood Is 90 Degrees. Also Used To Mark Wood.
Iron is denser than wood, i.e. it weighs more by volume.

Of course, this depends on the eraser. Generally 1 or 2 cm.
Density= Volume/Mass. Therefore: (9x2x6)divided by 5.4g=Density. 108cm/5.4g=Density. 20=Density.
A block of wood is sometimes used in the laboratory to elevate certain objects. Often, a lab-jack is used instead of a wooden block.
Density = Mass/Volume
No. It doesn't matter how heavy a block of wood is, it depends on the density of the wood. Generally wood floats as the density of wood is lighter than the density of the water, so it would float.

Density of wood = mass/volume
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?
A triple-beam balance can be used. The units could be g/ml the density of a normal wood is 0.88 but a wood block in density can be anything under 1 so it can be 0.95,0.54,etc. waters density is 1 and would can float on water so wood is anything below 1.
Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water. -- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced its entire weight in water, and floats. -- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.
Carpentars use math many times when: * Using a measuring tape * measuring a block of wood * how long to cut a block of wood * when talking about sizes of wood * and when talking about cords of firewood
A block of wood can be of different sizes; this will affect the mass, and weight, a lot. To a lesser degree, the weight of a block of wood will also depend on the density, since different types of wood have different densities.
