Volume • The volume is a measure of the space inside a solid object. • Volume is measure of 3 dimensions. • The units of volume are cube length or length3. • Example of volume units are cm3, cubic feet, cubic meters or inches3.
Surface Area • Surface area is the flat area on the surface of a three-dimensional object. • What you do is calculate the area of all the sides of an object and then add them up. • The units of volume are squared length or length2. • Example of volume units are cm2, squared feet, squared meters or inches2.
The cylinder • The volume of the cylinder is height of the cylinder times the area of a circle. V = πr2h. • The surface area of a cylinder has two parts. The ends are circles so each circle has an area of πr2. The lateral surface can be thought of as a rectangle wound into a circle. One side of the rectangle is h, the other side is the circumference of the circle which is 2πr. 2πr h h
