  1. Starter Questions Q1. 35% of 360 Q2. Calculate 5 + 6 x 7 Q3. Expand 2( y – 5 ) 1

  2. Volume of Solids Prisms LearningIntention • To understand the prism formula for • calculating volume.

  3. Volume of Solids Definition : A prism is a solid shape with uniform cross-section Hexagonal Prism Cylinder (circular Prism) Triangular Prism Pentagonal Prism Volume = Area of Face x length

  4. Any Triangle Area h = vertical height b Sometimes called the altitude h 4

  5. Any Triangle Area 8cm Example 1 : Find the area of the triangle. 6cm Area = 24cm²

  6. Volume of Solids Definition : A prism is a solid shape with uniform cross-section Q. Find the volume the triangular prism. Triangular Prism Volume = Area of face x length = 20 x 10 = 200 cm3 10cm 20cm2

  7. Triangle Area = 4cm 10cm 4cm Volume of a Triangular Prism Working = 2 x4 = 8 cm2 Volume = Area x length = 8 x 10 = 80cm3 Find the volume of the triangular prism

  8. Triangle Area = 6cm Example Find the volume of the triangular prism. Working = 3 x 3 = 9 cm2 Volume = Area x length = 9 x 30 = 270cm3 3cm 30cm Total Area = 6+6+30+40+50 = 132cm2

  9. Volume of Solids Now try Ex 5.1 Pg 30 Ch 2
