Answer: The number of 2 times 2 times 2 cm cubes is 14. The total surface area of all the 2 times 2 times 2 times cm cubes is 336 cm square. The total volume of all the 2 times 2 times 2 times cm cubes is 112 cm cube.
Explanation:
It is given that the A rectangular prism is 7 cm long, 4 cm wide and 4 cm tall.
The volume of rectangular prism is,
Therefore, the volume of rectangular prism is 112 cm square.
The volume of cubes is,
The number of cubes in the rectangular prism is,
Therefore, the number of cubes is 14.
Total surface area of a cube is,
Total surface area of all cubes is,
Therefore the total surface area of all cubes is 336 cm square.
Total volume of all cubes is equal t the volume of rectangular prism, i.e, 112 cm cube.
