1.)

***it gives me one measurement of the side of the cube which is 8 cm
1. A cubic block of granite shown in the figure has a density of 2.75 g/cm3. Find its mass.

A. 186.18 g
B. 176 g
C. 514.75 g
D. 1408 g

Answer 1

Option D.
`1,408\ g`

Explanation:

we know that

The density is equal to divide the mass by the volume

`D=(m)/(V)`

solve for m (mass)

`m=DV`

step 1

Find the volume of the cubic block of granite

`V=8^(3)=512\ cm^(3)`

step 2

Find the mass

substitute the values

`m=(2.75)(512)=1,408\ g`
