214 divided by 23 is 9.3 or 9 with remainder 7.
6. To check for divisibility by 9, add the digits of the number together and if the sum is divisible by 9, then the original number is divisible by 9. If the test is repeated on the sum(s) until a single digit remains, then this is the remainder when the original number is divided by 9. Subtracting this remainder from 9 will give the smallest number that needs to be added to to the original number to make it divisible by 9. For 75: 7 + 5 = 12 1 + 2 = 3 so 75 ÷ 9 has a remainder of 3, therefore add 9 - 3 = 6 to 75 to make it divisible by 9. (75 + 6 = 81 = 9 x 9).
The volume of a cube is calculated using the formula ( V = s^3 ), where ( s ) is the length of one side of the cube. To find the side length when the volume is 81, you can take the cube root of 81: ( s = \sqrt[3]{81} ). Since ( 81 = 3^4 ), the cube root is ( 3^{4/3} = 3 \times \sqrt[3]{3} ), which is approximately 4.33. Therefore, the length of each side of the cube is approximately 4.33 units.
