If all the gold that has been produced in
the last 500 years could be melted to
form a single cube, each side would
measure about 16 m. How many cubic
meters of gold is this?

4096 cubic meters

Step-by-step explanation:

16*16*16 = 4096

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
