Explain the advantages and disadvantages of using hardwoods in indoor furniture Advantages: appealing grain, generally strong and durable Disadvantages: expensive, hard to work on 2. State a suitable hardwood to be used in outdoor furniture.

Explain how plywood is manufactured. Use sketches to help explain Possible answer: Composed of individual plies or veneers Very strong due to the way plies are layered The grains of the plies are positioned at 90 degrees to the plies above and below it The plies are glued together An odd number of plies are used Plywood is less likely to warp due to this construction 6. Explain two advantages of using manufactured boards Generally more stable to timbers i.e. don t warp Cost- effective Can be worked with common woodworking tools 5
