Answer 1

Answer:

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

Explanation:

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

$d=\frac{m}{v}$

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.

$d=\frac{4240 \ g}{1564 \ cm^3}$

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.
