Hum, this problem was difficult. You use the next expression to solve this problem. \[\cos (A - B) = \cos A \cos B + \sin A \sin B \] \[\cos (A + B) = \cos A \cos B - \sin A \sin B\] \[\cos (A - B ) - \cos (A +B ) =2 \sin A \sin B\] So \[\sin A \sin B = 0.5 \left( \cos(A - B) - \cos(A + B) \right)\] A = 1.8 x, B = 0.5 x \[\sin (1.8x) \sin (0.5x) = 0.5\left( \cos(1.8-0.5)x - \cos(1.8+0.5)x \right)\]\[= 0.5 \left( \cos(1.3x) - \cos (2.3x) \right)\] It's finish !!

Answer:
The volume of diamond is 20 cubic inches.
Step-by-step explanation:
We are given the following in the question:
Triangular base:
Base = 4 inches
Height = 5 inches
Height of the pyramid = 6 inches
Area of triangular base =
Volume of diamond = Volume of pyramid
Thus, the volume of diamond is 20 cubic inches.
