Question

125 sweets boxes need to be wrapped . Find the length of packing paper of width 30 cm needed to wrap the sweet boxes of dimensions 12cm ×8cm×6cm​

Answer 1

125+30*12*8*6*cm ans is 15445

Answer 2

Answer:

length = 12cm , breadth = 8cm , height = 6cm

AREA OF 1 SWEET BOXE = 2*(lb + bh + hl)

=2*(12*8 + 8*6 + 6*12)

= 2*(96+48+72)

= 2*216

= 432cm^2

so,

the area of 125 sweet boxes = 432*125

= 54000cm^2

than,

l = find (?) , breadth = 30cm

the area of packing paper = 54000cm^2

l*b = 54000

or, l x 30 = 54000

or, l = 54000÷30

or, l = 1800 CM {converte CM to m}

or, l = 1800 ÷ 100

or, l = 18 m ^2

warning in book ans is wrong plz check 9m is wrong ans
