Question

plese help ylll question number 1​

Answer 1

1)From the question , we have

length (l )=1.5 m

breadth (b) =1.25m

Height(h)=65cm=0.65m

Area of sheet required for making the box = 2(lb + bh +lh) sq.units

=2(1.5×1.25+1.25×0.65+1.5×6.5) m^2

=2(1.875+ 0.8125 + 9.75)m^2

=5.45m^2

2) Since ,1 m^2 sheet costs Rs.20.Therefore,

Cost of sheet required for making the box =Rs.20×5.45 =Rs.109
