The figure shows a rectangular glass container partly filled with 20-cm cubes. After adding 4 extra cubes,
- How many more cubes are needed to the container completely?
- What is the volume of glass container?
(a)
Total number of cubes that can fill the container
= 4 x 2 x 3
= 24
Number of cubes in the container after adding extra cubes
= 12 + 4
= 16
Extra cubes to fill
= 24 - 16
= 8
(b)
Volume of one cube
= 20 x 20 x 20
= 8000 cm
3 Volume of the container
= 24 x 8000
= 192000 cm
3 Answer(s): (a) 8; (b) 192000 cm
