Answer»

Dimension of bookLength l = 8 inchWidth b = 5 inchHeight h = 1.5 inch

Then,Amount of wrapping paper required is equal to surface area of book

Surface area of book= 2(l*b + b*h + l*h)= 2(8*5 + 5*1.5 + 8*1.5)= 2(40 + 7.5 + 10.5)= 2(58)= 116 inch

Therefore,Wrapping paper required = 116 inch
