How to find the Volume of rectangular prisms

This week we are beginning our study on Volume. To complete this standard, we will combine learning the formulas for volume and our multiplication skills.  There are two different formulas that we will use.  The first is V = l x w x h.  The second formula is V = B x h.  B stands for the area of the base.  See the examples below to help you.    

On this example the area of the base (B) is 10 because on the first level of block, we have a length of 5 cm and a width of 2 cm.  Therefore, 2cm x 5cm = 10 squared centimeters. The next step is to multiply the object's height to the area of the base (B).  So, 10 cm2 x 2 is equal to 20 cm3.  Click on this Study Jams link to review and practice the skill.
