Answer:

x=√9=3

Step-by-step explanation:

ratio =4:5:6

let ,

l=6x. b=5x. h=4x.

2(lb+bh+lh)

2[(6x × 5x) +(5x ×4x)+(4x ×6x)]

2(30xsq)+ (20xsq)+(24xsq)

2(74xsq)

148xsq.msq

cost of making the box @rup 11=

148x sq ×11

=1628xsq

cost of making the box @rup 12.50=

148xsq ×12.50

= 1850x sq

acc to question,

1850x sq -1628xsq= 1998

222xsq=1998

xsq=1998\222

x*=9

x=√9=3
