Question

please give answer fast of these two​

Answer 1

Answer:

according to question :-

area of colour paper = area of cuboidal box

so

area of colour paper = 2(lh + bh + lb)

area = 2(16*12 + 12*5 + 16*5)

area = 2(192 + 60 + 80)

area = 2(332)

area = 664 cm ^2

so area of colour paper = 664cm^2

now

7. according to question :-

area of cuboid = 2(18*15 + 15*6 + 18*6)

area = 2(270 + 90 + 108)

area = 2(468)

area = 936m^2

now if

1m^2 = 20

then

936 = 20*936 = ₹18720
