Given, dimensions of the plastic box

Length, l = 1.5\ m

Width, b = 1.25\ m

Depth, h = 65\ cm = 0.65\ m

We know, area of the sheet required for making the box is 5.45\ m^2

(ii) Cost for  \small 1m^2 of sheet = Rs 20

\therefore Cost for 5.45\ m^2 of sheet = 5.45\times20 = 109

Required cost of the sheet is Rs.\ 109
