Multiple Choice

Set up a triple integral for the volume of the solid bounded by the coordinate planes and the plane given below. $z = 12 - 6 x - 8 y$

A) $\int_{0}^{2} \int_{0}^{\frac{12-6 x}{8}}\int_{0} ^ {12-6x-8y}dzdydx$

B) $\int_{0}^{2} \int_{0}^{\frac{12-6 x}{8}}\int_{0} ^ {12-6x-8y}dydzdx$

C) $\int _ { 0 } ^ { 12 } \int _ { 0 } ^ { \frac { 12 - 6 x } { 8 } } \int _ { 0 } ^ { 12 - 6 x - 8 y } d z d y d x$

D) $\int _ { 0 } ^ { 2 } \int _ { 0 } ^ { \frac { 12 - 6 x } { 8 } } \int _ { 0 } ^ { 12 - 6 x - 8 y } d x d y d z$

E) $\int_{0}^{\frac{12-6x}{8}} \int_{0}^{2}\int_{0} ^ {12-6x-8y}dzdydx$
