The shadow of a building is 8 meters long on level ground. The building and the ground are perpendicular to each other. The angle of elevation from the tip of the shadow to
the top of the building is 42 degrees. Based on this information, calculate the height of
the building.

Consider a cube that has sides of length l. now consider putting the largest sphere you can inside this cube without any point on the sphere lying outside of the cube. the volume ratio -volume of the sphere/ volume of the cube is 1. 5.2 × 10−1 2. 3.8 × 10−1 3. 1.9 4. 2.5 × 10−1 5. 3.8
