#### Transcript of Volume of Prisms

Volume of Prisms
Starter
Example
Find the volume of this trapezoidal prism.
Examples
Find the volume of these prisms
L.O. - Calculate the volume and surface area of prisms.
What is the best way to count the number of cubes in each shape?
Starter
Cuboid - Number of cubes = 2 x 5 x 3
Number of squares = (3 x 2 + 5 x 2 + 3 x 5) x 2
Blank prism - Number of cubes = (5 + 3 + 2 + 1) x 4
Number of squares = 11 x 2 + 18 x 4
Coloured prism - Number of cubes = (3 x 4 + 3) x 3
Number of squares = 15 x 2 + 16 x 3
Examples
Find the surface area and volume of these prisms
Volume = 14 x 8 = 112 cm

Example
Find the volume of this trapezoidal prism.
Area of = (14 + 8) x 4 = 44 cm
trapezium

Volume of = 44 x 10 = 440 cm
