Answers
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
(200-5)(120-5)(75-5) = 1569750 cm^3 = 1.56975 m^3
Now use that to find the cost
yes
1350
