Answer is 9.

-3x^2 + 243 = 0
Bring 243 to the right.
-3x^2 = -243
Divide by -3.
x^2 = 243/3 = 81
Tak the square root of both sides.
x = 81^1/2 = 9.

Volume=2.7million km^3
Base=339milliom km^2

$\\ \tt\longmapsto Volume=Base\times Height$

$\\ \tt\longmapsto Height=\dfrac{Volume}{Base}$

$\\ \tt\longmapsto Height=\dfrac{2.9km^3}{339km^2}$

$\\ \tt\longmapsto Height=0.00079km$

$\\ \tt\longmapsto Height=7.9m$
