To measure the mass of a metal cube. First find it's volume, V = L (length) x W (width) x H (height), since it's a cube the L, W, and H are all the same so, V= L^3= H^3= V^3. Then you look up the density in a table or on the internet and multiple the density by volume to get mass. V = L (length) x W (width) x H (height) m = V * density (row)

The formula for density:

density = mass / volume.

Volume of a cube = edge3

You could then need to find the mass of the cube and substitute the values into the density formula.

Assuming the metal is pure, its density should provide a clue as to its identity.

Density = mass/volume

= 15.4 /(1.2)^3

= 8.9 g/cm3

From density of metals table:

Copper has a density similar at 8.96 g/cm3

Nickel and Cobalt both have a density of 8.9 g/cm3

Bronze (an alloy) could also have a density of 8.9 g/cm3

Make sure the volume is in milliliter units and then multiply it by the density of the cube and you will get the mass of the object in grams. That is because density=grams/milliliters, so grams=density•milliliters

What is the de Broglie wavelength in meters of a baseball weighing 145 and traveling at 152?

You can use De' Broglie's equation. I think it is wavelength = plank's constant/mass of the object *velocity.velocity is unknown in this case, m= 154g and wavelength is 0.450*10-90.450*10-9 = look up the value of plank's constant/ 0.145 kg* Velocity.Rearrange the equation to get velocity of an object.
