Surface Area and Volume Mrs. Hubbard Room 152

Volume  Volume is the amount of space inside an object.  Volume is measured in cubic units, since there are three dimensions to account for. Example: 30 cubic units 30 units

Calculating Volume  You can Calculate the Volume of a cube by multiplying the length x width x height Length = 4 Width = 4 Height = 4 Volume = 4x4x4 = = 16 x 4 = 64 cubic units

Surface Area  Surface Area is the total amount of area that covers a three-dimensional object.  Think about the total amount of wrapping paper it takes to cover an object assuming you don’t overlap any of the paper.

Calculating S.A  Calculating the surface area of an object is easy, but it does take some time.  You can calculate surface area by finding the area of each face of the object, then adding all the areas together.  Your units for S.A are square units since you are measuring Area.

Let’s Try It! The cube has 6 sides. So, when we find the AREA of one side or face, we can just multiply that number by 6. The front face has dimensions, 4 units by 4 units. So, the Area of the front face is equal to 4x4= 16 square units. 16 square units x 6 = 96 Surface Area = 96 square units
