VOLUME AND SURFACE AREA OF SOLIDS
When working with 3-D shapes we can find the volume of the shapes. The volume is the capacity that the shape can hold. It is measured in cubic units. We can also find the surface area of the shape. The surface area is the total area of all the faces on the shape. Surface area is measure in square units.
To compute the volume of a rectangular prism, find the area of the base (length times width), and then multiply by the height to find the capacity of the prism in cubic units.
To compute the surface area of a rectangular prism, find the area of each of the faces, and then add them together to find the total number of square units.
To compute the volume of a cylinder, find the area of the circular base, and then multiply by the height to find the capacity of the cylinder in cubic units.
To compute the surface area of a cylinder, find the area of the two circular bases, and the area of the curved rectangular body, and then add them together to find the total number of square units.
