Question

It requires 1322 cm long ribbon to tie a cube gift pack . Find the length of the gift pack if 50 cm ribbon is used in the flower knot perimeter equals to 1322-50/2

Answer 1

Answer:

10.3cm

Step-by-step explanation:

If it is cuboid  

Surface area = 1322-50/2

=636cm

Total surface area of cuboid = 6a^2

636 = 6a^2

636/6 = a^2

106 = a^2

√160 = a

10.3 = a [approx]

The length of cube = 10.3cmIf it is cuboid  

Surface area = 1322-50/2

=636cm

Total surface area of cuboid = 6a^2

636 = 6a^2

636/6 = a^2

106 = a^2

√160 = a

10.3 = a [approx]

The length of cube = 10.3cm

Answer 2

Heya !!

Here's your answer......

____________________________

Surface area = 1322 - 50 / 2

= 1272 / 2

= 636


And , total surface area of a cuboid is 6a²

Then , 6a² = 636

a² = 636 / 6

a² = 106

a = √106

•°• Answer = √106
