Dear Student,

Please find below the solution to the asked query:

Given : Side of white card board cube  =  12 m = 50 cm   ( We know 1 m  = 100 cm )

We know surface area of cube = 6 ( Side )2 , So

Surface area of given white board cube = 6 ( 50 )2 = 6 ( 2500 ) = 15000 cm2

Also given area covered by a blue star =  40 cm2

But we do not have any information about pattern formed or what number of blue star used .

So, we can't solve it further , Kindly recheck your query and get back to us so that we could help you precisely .
