1. VOLUME Lesson Objective By the end of the lesson I should be able to Find the volume of a rectangular prism

2. Volume Units of volume mm 3 cm 3 m 3 km 3 The volume is the space within the inside of a 3D shape.

3. Rectangular Prism We can find the volume of a rectangular prism by multiplying the area of the cross-section (front rectangle) by the length. Volume of a cuboid = length × width × height = lwh height, h length, l width, w The area of the rectangle = length × width So, = ldh we use depth or breadth instead of width

4. Volume of a rectangular prism= length x height x width 5cm 20cm 4cm 5 x 20 x 4 = 400cm ³ 3cm 10cm 2cm 3 x 10 2 = 60cm³

5. Find the volume of these cuboids 6cm 4cm 2cm 7cm 5cm 3cm 10cm 5cm 4cm 3cm 8cm 2cm 48cm³ 200cm³ 105cm³

6. Height 10 cm Depth 8 cm Width 3 cm Height Width Depth Volume 240 cm³

7. Height 11 m Depth 8 m Width 5 m Height Width Depth Volume 440 m³m³

8. Height 10 cm Depth 8 cm Width 5 cm Height Width Depth Volume 400 cm³

9. Height 15 cm Depth 8 cm Width 1 cm Height Width Depth Volume 120 cm³
