This document discusses surface area and volume formulas for basic geometric shapes including rectangles, cuboids, cubes, cylinders, spheres, and hemispheres. It provides the formulas to calculate the total surface area and volume of each shape using length, width, height, radius, and other key measurements. Formulas covered include area of a rectangle, surface area of a cuboid, cube, cylinder, sphere, and hemisphere as well as volume of a cuboid, cube, cylinder, sphere, and hemisphere.
