i'm guessing the answer is in the question.
16 foot x 16 foot deck would be 256 square feet.
16 pounds
Every 16 inches
In math class: Draw a 16 cm long for the base. At each end draw a perpendicular line straight up 8 cm long for the sides. Connect straight across, this should be another 16 cm line. In building/construction. Lie out a 16 foot board for the base. Attach (nail on) a board to make both ends 8 feet long. Measure the diagonals until each is the same length then nail on the top board another 16 foot board. If the diagonals are equal you will have perpendicular sides.
If you are planning to build a wood deck for your house and do not want to worry about measuring and cutting lumber, consider plans to build a 16 foot by 16 foot deck. To build this simple square shape, the majority of the lumber you will need will be in the form of 8 foot planks. If you do not have a saw, have the lumber center cut the boards into the lengths you need. Then simply lay out two rows of 8 foot lengths so they measure 16 feet both vertically and horizontally.
FOUR
Assumption: 6 x 6 is using inches as the unit (half a foot) and a 4 foot board means 4 square feet of board. Each square foot of board can be cut into four half foot x half foot pieces. Therefore, the 4 foot board would be able to make 16 half foot x half foot (6 inch x 6 inch) blocks.
16 foot
Area = 16 x 30 = 480 sq feet
How long are the 2x10's, what is supporting the deck and how is the deck attached to that support. A lot of factors go into figuring load limits.
It is 1/16 of real size. If something is 16 feet long, say a small car, the model will be 1 foot long.
4 foot high by 8 foot long by width of the of the cut wood (usually 16 inches)
