Answer 1

`\boxed {\tt d\approx 2.7 \ g/cm^3}`

Step-by-step explanation:

Density can be found by dividing the mass by the volume.

`d=(m)/(v)`

The mass of the marble slab is 4.24 kilograms.

The density is 1564 cubic centimeters.

Since we want to find the density, in g/cm^3, we must convert kilograms to grams. There are 1000 grams in 1 kilogram, so multiply 4.24 by 1000.

• 1000 g= 1 kg

• 4.24*1000=4240 grams

Therefore,

`m= 4240 \ g \\v= 1564 \ cm^3`

Substitute the values into the formula.

`d=(4240 \ g)/(1564 \ cm^3)`

Divide.

`d= 2.71099744 \ g/cm^3`

Round to the nearest tenth. The 1 in the hundredth place tells us to leave the tenth place as is.

`d \approx 2.7 \ g/cm^3`

The density is about 2.7 grams per cubic centimeter.
