Find the Triple Scalar Product A) $\mathbf { u } \cdot ( \mathbf { v } \times \mathbf { w } ) = 120$

Multiple Choice

Find the triple scalar product. $\mathbf { u } = 10 \mathbf { i } + 11 \mathbf { j } + 11 \mathbf { k } , \mathbf { v } = 9 \mathbf { i } + 10 \mathbf { j } , \mathbf { w } = 9 \mathbf { i } + 11 \mathbf { j } + 20 \mathbf { k }$

A) $\mathbf { u } \cdot ( \mathbf { v } \times \mathbf { w } ) = 120$
B) $\mathbf { u } ( \mathbf { v } \times \mathbf { w } ) = 121$
C) $\mathbf { u } \cdot ( \mathbf { v } \times \mathbf { w } ) = 119$
D) $\mathbf { u } \cdot ( \mathbf { v } \times \mathbf { w } ) = 118$
E) $\mathbf { u } \cdot ( \mathbf { v } \times \mathbf { w } ) = 117$
