Question

A granite monument has a volume of 25,365.4cm3. The density of granite is 2.7 g/cm3. Use this information to calcute the mass of the monument to the nearest tenth

Answer 1

68,486.6

Step-by-step explanation:

Answer 2

V = 25,364.4 cm³ Is the volume

r = 2.7g/cm³ Is the density

To calculate mass you use formula:

m= V*r

To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm³ and cm³. If we multiply them, we negate cm³ and cm³ and we are left with g which is unit for mass.

Therefore the answer is m = 68,486,6 g
