The figure shows a rectangular glass container partly filled with 12-cm cubes. After adding 6 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 + 6
= 18
Extra cubes to fill
= 24 - 18
= 6
(b)
Volume of one cube
= 12 x 12 x 12
= 1728 cm
3 Volume of the container
= 24 x 1728
= 41472 cm
3 Answer(s): (a) 6; (b) 41472 cm
