Answer: x=2

Step-by-step explanation:

subtract 10x from 6x

Add -8x to both sides of equation

Add -4x and 8x

4x-2=6

Add 2 to both sides of equation

4x =6+2

Add 6 and 2

4x=8

Divide each term by 4 and simplify

X=8/4

Divide 8 by 4

X=2

Answer:

$V_{cube} = 64,000 \: {m}^{3}$

Step-by-step explanation:

Surface area of cube

$= 6 {a}^{2} \\ (where \: a = side \: length \: of \: cube) \\ \\ \therefore \: 9600 = 6 {a}^{2} \\ \\ \frac{9600}{6} = {a}^{2} \\ \\ 1600 = {a}^{2} \\ \\ a = \sqrt{1600} \\ \\ a = 40 \: m \\ \\V_{cube} = {a}^{3} \\ \\ V_{cube} = {(40)}^{3} \\ \\ V_{cube} = 64,000 \: {m}^{3}$
