The surface area and the volume of pyramids, prisms, cylinders and cones, the surface area is the area that describes the material that will be used to cover a geometric solid. The volume is a measure of how much a figure can hold and is measured in cubic units. The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid, we take the sum of the area for each geometric form within the solid. The volume is a measure of how much a figure can hold and is measured in cubic units. When we determine the surface areas of a geometric solid, we take the sum of the area for each geometric form within the solid. The volume is a measure of how much a figure can hold and is measured in cubic units. The volume tells us something about the capacity of a figure. The concepts covered in the chapter include surface areas and volumes of combinations of any two of the following: cubes, cuboids, spheres, hemispheres and right circular cylinders/ cones, frustum of a cone etc.
