Joseph Sheard sat for a mensuration exam at the Bendigo School of Mines, in 1908, achieving a 67 percent mark. Mensuration is a branch of mathematics that focuses on measuring geometric figures. It involves calculating attributes such as area, volume, and perimeter for both 2D (plane) shapes and 3D (solid) objects. Key concepts in mensuration include formulas for calculating the area of shapes like squares and circles, as well as the volume of solids like cubes and cylinders. Additionally, mensuration is often applied in practical scenarios, such as architecture and engineering, to determine material requirements and space utilization.Hand drawn design in black pen, on light tan paper.
