Volume Review

Page 32: Friday,  February  24 th

What is It?!?!

•Volume- The number of cubic units needed to Fill a space

•Volume is measured in cubic units (ex: in3)

Page 33: Friday,  February  24 th

Rectangular Prisms • **To find the volume of a rectangular prism,

multiply the area of the base by the height

V=BhB is the area of the base

Page 34: Friday,  February  24 th

BASERectanglur Prism: When the Base is a rectangle- to find the B, use L x W, then multiply by the height of the prism

Cylinder: When the Base is a circle- to find the B, use A=πr2…then multiply by the height of the cylinder

Cube: is a special type of rectangular prism. We can use the formula V=s3 to find the volume, where s=side length

Page 35: Friday,  February  24 th

Helpful Hint

ALWAYS write the formula, plug in your values, and

carefully multiply. CHECK YOUR UNITS!!!
