# If the density of a block of wood is 0.5 cm3 what is the volume of the block if its mass is 27 g?

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

### What is the density of a block of wood has a mass of 4g and occupies a volume of 5cm3?

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…

### What is the Density of a 750 g block of wood measuring 12cm x 8cm x 9cm?

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…

### If the volume of one block of wood is greater than that of a second block of wood but the mass of the second block is great Which has a greater density and why?

Density= Mass/Volume If we insert arbitrary figures ... Block 1 Volume 40 cubic cms [arbitrary] Block 1 Mass is less than Block 2 so 39 gms Block 2 Volume is less than Block 1 so 39 cubic cms Block 2 Mass 40 gms [arbitrary] D1 = 39/40 = 0.975 grams/cubic cm D2 = 40/39 = 1.0256 grams/cubic cm It's clear therefore than inserting extra matter [mass] into the same volume or a lesser volume results…

### How do you find mass when you have density and volume?

You can think of the answer to this from your real life experience; As you know, here on the ground (I'm assuming you're on the ground), anything with mass has weight. Even in outer space, things with more mass take more effort to move around. You know from experience that a block of metal is more dense than a block of dry wood of the same size, because it's heavier and harder to move around…

### 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/cmÂ³, then compare this to 1 g/cmÂ³.

### What part of the block of wood remains immersed in water of density 1000kg per cm cube when the block of wood placed in water has density 700 Kg per m cube?

-- 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.
