To Find the Area of Composite Shapes, like the one shown, you simply...

• Divide the shape into simple known shapes, find the area of each shape, and add the areas together.

• Create a new shape and find the area of that shape.

• Divide the shape into simple known shapes, find the area of each shape, and multiply the areas together.

• Find the area of each shape and subtract the areas of the smaller shapes from the largest shape.

Surface area is...

• The area of all sides of a three-dimensional shape added together.

• The amount of space inside a 3-dimensional shape.

• The area of a two-dimensional shape.

• The area of just the top and bottom of a three-dimensional shape.

Lateral Surface Area is...

• The area of just the sides of a three dimensional shape. Take the areas of each side of the shape and add them together.

• The area of just the top and bottom (bases) of a three dimensional shape added together.

• The area of a two dimensional shape.

• The area of all the sides, including bases, of a three-dimensional shape all added together.
