Answer:
The mass of the cubic granite block is 1408 g .
Step-by-step explanation:
Formula
Volume of a cube = a³
Where a is the side of the cube .

As given
one side of the cube is 8 cm .
(The figure is shown below.)
Thus
Put in the formula
Volume of a cubic granite block = 8 × 8 × 8
= 512 cm³
As given
The density of cube is 2.75 g/cm³.
Put in the formula

Mass = 2.75 × 512
Mass = 1408 g
Therefore the mass of the cubic granite block is 1408 g .
X =
First, before we can add, we have to find a common denominator.
We can use 24.
7 7/8 x 3/3 = 7 21/24
2 1/3 x 8/8 = 2 8/24
Now we add.
7 21/24 + 2 8/24 = 9 29/24 (denominator stays the same)
Lastly, simplify
9 29/24 = 10 5/24
