The third one down is the correct answer. (-55 and 1)
Step-by-step explanation:
the shape has been split into 2 shapes. one cuboid and a triangular prism . work out the volume of each shape .
hint : volume : h×l×w ( height times length times width)
so the cubiod is 12 times 29 times 12 =
you work out the answer for that .
the triangular prism you try working out the volume.
The inverse function of cos is arccos (cos^-1(x)). So, the only one that has arccos(x/6) is option c. That's your answer!
