Volume and Surface Area of Composite Solids

The figure below shows a solid of a uniform cross section, where the circular portion is a quadrant, and an isosceles right-angled triangular prism is removed from the solid. Find, correcting your answers to the nearest integer,

1. the area of the cross section in cm\(^2\),
2. the total surface area of the solid in cm\(^2\), and
3. the volume of the solid in cm\(^3\).

The source labels the sloping cut as 240 mm. This is rounded: its two perpendicular sides are 170 mm, so the exact sloping length is \(170\sqrt2\text{ mm}\). Use the exact sloping length before rounding the requested answers.
