Because the 23 cm side can fit in 11, rather than 10, of such cubes.
In other words, we can fit in
10 x 11 x 5, or
550 cubes.
In other words, we can fit in
10 x 11 x 5, or
550 cubes.
Number of cubes that can be fitted along 20cm side
= 20cm ÷ 2cm
= 10
Number of cubes that can be fitted along 10cm side
= 10cm ÷ 2cm
= 5
Number of cubes that can be fitted along 23cm side
= 23cm ÷ 2cm
= 11 R 2
Total number of cubes that can be fitted
= 11 x 10 x 5
= 110 x 5
= 550
= 20cm ÷ 2cm
= 10
Number of cubes that can be fitted along 10cm side
= 10cm ÷ 2cm
= 5
Number of cubes that can be fitted along 23cm side
= 23cm ÷ 2cm
= 11 R 2
Total number of cubes that can be fitted
= 11 x 10 x 5
= 110 x 5
= 550
You mean 11 R 1 (likely a mis-pressing of a button or a keyboard)
Yes. Sometimes calculation too fast.
To be more accurate, 11 R 1cm
To be more accurate, 11 R 1cm
Many thanks for the answer :)

20➗2= 10
23➗2 = 11 R 1
10 ➗2 = 5
10 x 11 x 5 = 550 ( 2 cm cubes)
( you must only take the quotients and multiply) not the remainder
23➗2 = 11 R 1

Thank you very much. :)
