15X3cmX1cmX3cmX5cm=61
It depends on the density of the material of which the bar is made.
density = mass / volume volume of cube = 1cm x 1cm x 1cm = 1cm3 density = 0.8g / 1cm3 = 0.8g/cm3
Density = mass/volumeFor the cube of water having a mass of 1g:Volume of a cube of water measuring 1cm X 1cm X 1cm =1cm3.Density = 1g/1cm3 = 1g/cm3For the block of "plasting" having a mass of 4g:Volume of the block of plasting measuring 2cm X 3cm X 1cm = 6cm3.Density = 4g/6cm3 = 0.7g/cm3I will let you decide which has the greatest density.
Area of a rectangle= Length * width Length= 5cm Width= 1cm Area=5cm *1cm =5cm2
18 cm3.
The area of rectangle is : 3.0
First convert mols to grams, then divide the mass by the density.
It is a rectangle.
You've got (50cm x 20cm x 1cm) = 1,000 cm3 there. (That's a liter !)Since its density is 7.5 times the density of water, its mass is 7.5 kg .It weighs 73.6 newtons (16lb 8.55oz).
To calculate for the volume, you multiply (L x W x H). So with this problem (6cm x 3cm x 1cm) = 18 cm. So Volume = 18 cm3. For density, the equation is D= M/V. With this problem, the mass (M) is 36g, and the volume is 18cm3. So now we could calculate for the density. 36g/18cm =2g/cm3
if the rock is as you say then you could turn it into 3cm cubed and a mass of 30 grams. that means that it is 1cm cubed and a mass of 10 grams, so that means the density is 10 g/cc,while water's is 1 g/cc , finally the rock is ten times heavier then the water.
Assuming that the solid is a cuboid (not an ellipsoid, for example), its volume is 10*1*5 = 50 cm3. Therefore its density = mass/volume = 500/50 = 10 grams per cm3
