Answer 1

Answer:

surface area = (bh) (bl) (hl)

• In bigger box

let breadth be in bigger box be 25

length be 20

height be 5.

• In smaller box.

let breadth be in smaller box be 15

length be 12

height be 5

so, surface area of bigger box is 6250000cm^3. surface area of smaller box is 810000cm ^3

total area = 7060000cm^3

• 5% related

we take the total area + 5%of total area

7060000cm^3 + 353000 cm^3 = 7413000cm^3
