Step-by-step explanation:
8x + 11=2(4x-7) + 25
8x + 11 = 8x - 14 + 25
8x + 11=8x- 14 + 14 +25 + 11
8x-8x + 11 -11 = 14 + 25 + 11
8x-8x =14 + 25 + 11
X = 50

Answer:
The density of cube is 6.17959 ![\frac{g}{cm^{3} }](https://tex.z-dn.net/?f=%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D)
Step-by-step explanation:
The density is given by ration of a mass of body and volume occupied by a body.
![\rho = \frac{m}{V}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7Bm%7D%7BV%7D)
Where,
is density.
m is mass of a body
V is the volume of a body
Given that one side of the cube is 0.53cm
Hence, the volume of a body is V=
=0.148877![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
Now, the Density of the cube will be
![\rho = \frac{m}{V}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7Bm%7D%7BV%7D)
![\rho = \frac{0.92}{0.148877}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7B0.92%7D%7B0.148877%7D)
![\rho =6.17959](https://tex.z-dn.net/?f=%5Crho%20%3D6.17959)
Thus, The density of cube is 6.17959 ![\frac{g}{cm^{3} }](https://tex.z-dn.net/?f=%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D)
