A wooden box measures 20cm by 12cm by 10cm. Thickness of
wood is 1 cm. volume of wood to make the box is.ÂSolution
l=20, b=12, h=10, and x =1 Volume of hollow cuboid = l× b× h –(l-2x) (b-2x) (h-2x)   --where, x is the thickness of walls of the cuboid = 20×12×10 – (20-2) (12-2) (10-2) =2400-18×10×8 =2400-1440= 960cm3
