= Exact marble block weight Show in

Weight of one block: 51.26
Volume of one piece: 20 000
Density used: 2563 kg/m3

Show the working

Length = 1000
Width = 200
Height = 100
Number of pieces = 1
volume_mm3 = 1000 * 200 * 100 = 20 000 000
Volume of one piece = 20 000 000 / 1000 = 20 000
Density used = 2563 = 2563
Weight of one block = 20 000 000 * 2563 / 1e9 = 51.26
Total weight = 51.26 * 1 = 51.26

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

Volume = length x width x height
Weight = volume x density, with density = 2563 kg/m3
One cubic millimetre of a material at 1000 kg/m3 weighs exactly one milligram, so the millimetre-to-kilogram step is a shift of the decimal point rather than a rounded factor.

Solid marble.

Dimensions are nominal. Mill tolerances on thickness, and the corner radii on formed sections, both move the real weight by a percent or two.

Every field takes inches or feet as readily as millimetres: change the unit next to it and the conversion is done exactly before the arithmetic starts.

Frequently asked

What is the density of marble?

2563 kg/m3, which is 2.563 g/cm3. Solid marble.

How do you calculate the weight of a marble block?

Volume = length x width x height. Multiply the volume by the density of marble, 2563 kg/m3, taking care that both are in the same unit system.

Can I enter dimensions in inches?

Yes. Each dimension field has its own unit selector, and inch, foot, millimetre, centimetre and metre entries are all converted exactly before anything is multiplied.

Where the numbers come from

Densities are nominal room-temperature values for the grade named, drawn from the usual mill and handbook figures.
