Answer 1

Answer:

Number of trees that will be planted by the students equal 3025

Step-by-step explanation:

There are three sections from each class that means from class one 1×1×1=1^3,2×2×2=2^3,........upto 10^3

${1}^{3} + {2}^{3} + ......... + {10}^{3} \\ = { \frac{ {n}^{2} (n +1)}{4} }^{2} \\ = {10}^{2} ( {11}^{2} ) \div 4 \\ = \frac{100 \times 121}{4} \\ = 3025$

Hope this is the answer
