Since beta is in the first quadrant, the final answer will be positive.

To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that

$\sin( \beta ) = \frac{ \sqrt{17} }{5}$

So, this means that

$\sin( \frac{ \beta }{2} ) = \sqrt{ \frac{1 - \frac{ \sqrt{17} }{2} }{2} } = \sqrt{ \frac{2 - \sqrt{17} }{4} } = \frac{ \sqrt{2 - \sqrt{17} } }{2}$

The following wedge prism has a volume of

tiny-mole [99]

Answer:

The volume of the prism is 27 cubic inches.

Step-by-step explanation:

In order to calculate the volume of the given prism, we need to apply the correct formula. The volume of the wedge prism is given by the following formula:

$Volume = \frac{1}{2}*b*h*l$

Applying the data from the problem on the equation above, we have:

$Volume = \frac{1}{2}*6*4.5*2\\Volume = 6*4.5\\Volume = 27$

The volume of the prism is 27 cubic inches.
