You have learnt how to find the surface and volumeof single regular solids only.we can however see that other object can be seen as combination of the soild shapes.so,we now haveto find their surface area and volumes .the table of the soild shapes, their areas and volumes are given below.

Try this

---

1. Break the pictures in the previous figure into soilds of known shapes.

2.Think of five more objects around you that can be seen as a combination of sjapes.name the shapes that combined to make them.
