Let tan x = a
7 tan^3 x - 21 tan x = 0 becomes
7a^3 - 21a = 0
7a(a^2 - 3) = 0
a = 0 or a^2 - 3 = 0
a = 0 or a^2 = 3
a = 0 or a = + or - √3

tan x = 0, tan x = √3, tan x = -√3
x = 0, pi, pi/3, 4pi/3, 2pi/3, 5pi/3

To find the area of a prism, you calculate the area of the cross-section and multiply that number by the length. The cross-section of this prism is a trapezium, and the formula for this is \frac{a+b}{2}h. 
Insert your given numbers to find out the area of this prism's cross-section:
\frac{3+12}{2}12=90
Now, multiply 90 by the length, 10cm, to find out the volume of the prism;
90×10=900cm³
Therefore, your answer id the third option.
