Cube and Cuboid 2
Practice and master this topic with our carefully crafted questions.
The following questions are based on the information given below:
1. A cuboid shaped wooden block has 4 cm length, 3 cm breadth and 5 cm height.
2. Two sides measuring 5 cm x 4 cm are coloured in red.
3. Two faces measuring 4 cm x 3 cm are coloured in blue.
4. Two faces measuring 5 cm x 3 cm are coloured in green.
5. Now the block is divided into small cubes of side 1 cm each.
Required number of small cubes = 6 from the top and 6 from the bottom = 12
2 from the front + 2 from the back + 3 from the left + 3 from the right + 6 from the top + 6 from the bottom = 22
Such cubes are related to the corners of the cuboid and in the cuboid there are 8 corners.
Hence, the required number of small cubes is 8.
Required number of small cubes = (5 - 2) x (4 - 2) x (3 - 2)
= 3 x 2 x 1
= 6
