Answer 1

Step-by-step explanation:

this is the correct answer

Answer 2

Question :-

If the side of cube is increased by 150%. Find the percentage increase in surface area. 1

Given :-

• Increased by 150%

Solution :-

Formula Used :-

Total surface area = 6a² ; a = edge of a solid cube

Calculation :-

→ Using above formula we got , intital surface = 6a²

Increase of a cube = a + 150% of a = 2.5 a

New Surface area :- 6 × ( 2.5 a)² = 37.5 a²

∴ Percentage increased in surface area :- ( 37.5 a² - 6 a² ) × 100/6a² = 525% increased.

★ Answer :- 525%
