One side 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

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 .

the solution is h=10 because you add 9 to each side of the equation.
