The diagram below (not drawn to scale) shows a metal statue that comprises of a closed half-cylinder that is mounted on a cuboid. The dimensions of the cuboid are \(1.1\text{ m}\) by \(0.2\text{ m}\) by \(2.5\text{ m}\). The radius of the semi-circular cross-section of the half-cylinder is \(1.5\text{ m}\) and the breadth is \(0.4\text{ m}\).

1. Find the volume of metal, in \(\text{m}^3\), used to make the statue.[3]
2. Find the total surface area, in \(\text{m}^2\), of the statue.[4]
