Answer 2

Answer:

ok

Explanation:

Let

original length be a'.

:. Original Surface Area * (S_{0}) = 6a ^ 2

Now, increase in the length =

SNeulexgth = a + (50/10 * a)

за 2

(S_{1}) = 6 * (3a)/2 * (3a)/2

279²

2

Increase in Surface Area = S₁ - So

= 2 152 2

Percentage of increase in Surface Area

152²
