1. Recapping Area
A = ½bh
A = b×h
A = πr2
A = ½h(a + b)

3. What is the volume of the cuboid?
What is the volume of the shaded triangular prism?
Is it true that the volume of a triangular prism can always be found by taking half of the volume of the cuboid which surrounds the prism?

4. Volume of Prism or cylinder = area of cross-section × length

6. Find the volume of this prism. L in this prism is also 7cm.
What is the volume of this Prism if L=7cm and h=5.8cm? (Notice that the base of the triangular face is 1.13L).
