For the volume, you will have to find the area of the trapezium minus the area of the circle first. Then by multiplying it with the depth, you will get the Volume.
As for the Total Surface Area, you will have to include not only the front, back, top, bottom, left and right surfaces, you will have to include the surface of the cylinder in the middle too.
