The surface area of an object is determined by multiplying the length times the width. The volume of a rectangular solid is also calculated using units of length. A cubic meter is a cube one meter on each side. You can determine the volume of rectangular solids by multiplying length times width times height. A graduated cylinder is a cylindrical container marked with lines from bottom to top.
Liquid volume is measured using a unit called a liter.
A liter has the volume of 1000 cubic centimeters. One milliliter of liquid would completely fill a cube measuring one centimeter on each side. Mass Scientists use balances to find the mass of objects in grams. You will use a beam balance similar to Figure 26 . Notice that on one side of the balance is a pan and on the other side is a set of beams.
