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
Area of a rectangle= Length * width Length= 5cm Width= 1cm Area=5cm *1cm =5cm2
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.
18 cm3.
The area of rectangle is : 3.0
It is a rectangle.
First convert mols to grams, then divide the mass by the density.
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 the volume of object A, multiply its length, width, and height: 6cm * 3cm * 1cm = 18 cm^3. To calculate the density, divide the mass by the volume: 36g / 18 cm^3 = 2 g/cm^3. Therefore, the volume of object A is 18 cm^3 and its density is 2 g/cm^3.
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
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.
