Let V Be the Volume of the Solid That Lies $y = 0$

Multiple Choice

Let V be the volume of the solid that lies between planes perpendicular to the x-axis from x = 0 to x = 3. The cross-sections of this solid perpendicular to the x-axis run from $y = 0$ to $y = 3 - x$ and they are squares with bases in the xy-plane. Then V is

B) 14
C) $\frac { 56 } { 3 }$
D) 9
E) $\frac { 32 } { 5 }$
