Volume of Solids Prisms LearningIntention • To understand the prism formula for • calculating volume.
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
Any Triangle Area h = vertical height b Sometimes called the altitude h 4
Any Triangle Area 8cm Example 1 : Find the area of the triangle. 6cm Area = 24cm²
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
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
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
