How many cubic-centimetre blocks will be required to build cubes/cuboids of the following dimensions?
❶ 4 cm by 8 cm by 7 cm.
❷ 4 m x 50 cm x 0.1 m.
❸ Length of an edge = 0.2m.
❹ Each side = 4 cm.
_______________________
Need solution for all four.
Answers
To Find :
The number of cubic centimeter blocks will be required to make these cubes/cuboids
- 4cm×8cm×7cm
- 4m×50cm×0.1m
- lenght of an edge = 0.2m
- Each side = 4cm
Concept:
In this question, it is asked that how many cubic centimeters block (block of volume 1cm³) are required to make the whole cube/cuboid. So, we need to find actually the volume of all the cube/cuboid in cm³ as for example :
Eg: Of a cube has a volume of 8cm³, we can wrote it as 8×1cm³. This means that, it is made up of 8 cubic centimeter blocks.
Solution :
1] Dimensions given :
4cm×8cm×7cm
So, Volume :
=> 4cm×8cm×7cm
=> 224 cm³
So, we can write it as :
224×1cm³,
which means that 224 blocks of 1cm³ are required to build this cuboid

2] Dimensions given:
4m×50cm×0.1m
4m = 400 cm
0.1m = 10 cm
So, Volume :
=> 400cm × 50cm × 10cm
=> 2,00,000 cm³
So, 2,00,000 blocks of 1cm³ are required to build this cuboid

3] Side of edge given = 0.2m
0.2 m = 20 cm
so, Volume :
=> 20cm × 20cm× 20cm
=> 8000 cm³
So, 8000 blocks of 1 cm³ are required to make this cube

4] Side lenght = 4cm
So, Volume :
=> 2cm × 2cm × 2cm
=> 8cm³
So, 8 blocks of 1cm³ are required to make this cube.
Answer:
❶ Answer :-
4×8×7
= 224 cm³
❷ Answer :-
4×50×0.1
0.1m = 10cm
=4×50×10
= 2000 cm³
❸ Answer:-
0.2m = 20cm
20×20×20
= 8000 cm³
❹ Answer:-
4×4×4
= 64 cm³
