Answer 1

Step-by-step explanation:

length of box =2.5

breadth = 1

height = 1

Now we find how much metal will be required to make this box?

Area =2X (bh+hl)+ lb

Area =2X(1X1+1X2.5)+2.5X1

Area=2X(1+2.5)+2.5

Area=2X2.5+2.5

Area=7.5msqr

cost to paint

13X 250

= 3,250

hence total cost is 3,250
