F10 – Unit 1 - MeasurementLesson 9 – Composite Objects
Composite Object - the result of combining two or more objects to make a new object
Finding Volume of Composite Objects
1) Split the shape into different objects2) Find the volume of each individual object 3) Add together the volumes of each shape
Example 1: Determine the volume of this composite object to the nearest tenth of a cubic centimeter.
Example 2: Determine the surface area of this composite object.
