Question

Write the cubes of numbers from $1$ to $30$.

Answer 1

Find the cubes of numbers from $1$ to $30$:

Cube of a number $x=x\times x\times x$.

$\begin{array}{rcl}{1}^3& =& 1\\ 2^3& =& 8\\ 3^3& =& 27\\ 4^3& =& 64\\ 5^3& =& 125\\ 6^3& =& 216\\ 7^3& =& 343\\ 8^3& =& 512\\ 9^3& =& 729\\ {10}^3& =& 1000\\ {11}^3& =& 1331\\ {12}^3& =& 1728\\ {13}^3& =& 2197\\ {14}^3& =& 2744\\ {15}^3& =& 3375\\ {16}^3& =& 4096\\ {17}^3& =& 4913\\ {18}^3& =& 5832\\ {19}^3& =& 6859\\ {20}^3& =& 8000\\ {21}^3& =& 9261\\ {22}^3& =& 10648\\ {23}^3& =& 12167\\ {24}^3& =& 13824\\ {25}^3& =& 15625\\ {26}^3& =& 17576\\ {27}^3& =& 19683\\ {28}^3& =& 21952\\ {29}^3& =& 24389\\ {30}^3& =& 27000\end{array}$

Hence, cube of numbers $1-30$ are $\begin{array}{rcl}& & 1,8,27,64,125,216,343,512,729,1000,1331,1728,2197,2744,3375,4096,4913,5832,6859,\end{array}$

$\begin{array}{rcl}& & 8000,9261,10648,12167,13824,15625,17576,19683,21952,24389,27000\end{array}$ respectively.
