14.5 Volume, Mass, and Temperature

 

Figure

 

RECALL: To find the surface area you count squares; NOW, to find volume you count cubes

 

S.A. → units are squares (i.e., square centimeters, square inches, .)

V. → units are cubes (i.e., cubic centimeters, cubic inches,..)

 

 

 

Volume of Right Rectangular Prisms

 

→ determine how many cubes are needed to build it (Figure)

 

Formula: V = lwh →→ B = lw

 

 

 

 

 

 

 

 

 

 

Volume of a Cylinder

 

Formula: V = Bh →→→ B =
