Answer 1

Answer:

Hey mate

This is ur answer

Answer 2

Answer:

a) lateral surface area =4a^2 = 4×(7) ^2 =4×49= 196cm^2

Total Surface area= 6a^2= 6×(7) ^2 =6×49= 294cm^2

Step-by-step explanation:

b) Lateral Surface Area- 4(a) ^2 =4(8) ^2= 4×64= 256 cm^2

Total Surface area= 6(a) ^2= 6×(8) ^2 =6×64 = 384

c) Lateral Surface Area= 4×25=100 cm^2

T. surface area= 6×25= 150cm^2
