Answer 1

assuming that the wood purchased will be used efficiently, the volume of wood is the outside volume less the inside volume. Since there are parallel sides, the inner dimensions are 5 cm less than the outer. Thus, the volume of wood is

(200-5)(120-5)(75-5) = 1569750 cm^3 = 1.56975 m^3

Now use that to find the cost
