Answer» Given: Length = 1.5 m,Breadth = 1.25 m and Depth = 65 cm = 0.65 m Area of the sheet required for making the box open at the top = 2(bh+hl)+lb = 2(1.250.65+0.651.5)+1.51.25 = 2(0.8125+0.975)+1.875 = 21.7875+1.875 = 3.575 + 1.875 = 5.45 m^2

Answer»

Given: Length = 1.5 m,Breadth = 1.25 m and Depth = 65 cm = 0.65 m

Area of the sheet required for making the box open at the top

= 2(bh+hl)+lb = 2(1.25*0.65+0.65*1.5)+1.5*1.25

= 2(0.8125+0.975)+1.875 = 2*1.7875+1.875

= 3.575 + 1.875

= 5.45 m^2
