Simple :)
Area of shaded part = are of 1/4 circle - area of both triangles.
Are of circle = pie r^2 so 100x3.14 = 314 cm2.
Area of triangle AOB= area of triangleDOE = bh/2= 5x10/2= 25 each
However, the traingles share a common area which is quad DOB(I)
Lets take traingle AOE, whose are is bh/2=10x10/2=50cm2.
50-area of triangle A(I)E= 50-(
You got this you can do it I don’t know the answer but I hope you find someone who does(:

Volume of rectangle prism = w l h
Volume of rectangle pyramid = 1/3(w l h)
so Volume of rectangle pyramid = 1/3 (Volume of rectangle prism)
= 1/3 (240)
= 80
Answer:
80 cm^3
