This document provides information on mensuration and geometry topics such as trapezoids, rhombuses, cubes, cuboids, cylinders, and their volume and surface area formulas. It includes an introduction to area and surface area concepts. Formulas provided calculate the surface area of a cuboid as 2(lb + bh + hl), a cube as 6l^2, and a cylinder as 2πr(r+h). Volume formulas given are for a cuboid as lxbxh, a cube as l^3, and a cylinder as πr^2h. The document also contains sample problems, diagrams, and a question bank testing knowledge of geometry and volume concepts.
