The edges of a parallelepiped are of unit length and are parallel to non-coplanar unit vectors a^,b^,c^\hat{a}, \hat{b}, \hat{c} such that a^⋅b^=b^⋅c^=c^⋅a^=12\hat{a} \cdot \hat{b} = \hat{b} \cdot \hat{c} = \hat{c} \cdot \hat{a} = \frac{1}{2}. Find the volume of the parallelepiped. a. 12\frac{1}{\sqrt{2}} cu unit b. 122\frac{1}{2\sqrt{2}} cu unit c. 32\frac{\sqrt{3}}{2} cu unit d. 13\frac{1}{\sqrt{3}} cu unit
