The maximum span for a 4x8 wooden beam typically ranges from 10 to 14 feet, depending on factors such as the type of wood, load requirements, and the beam's orientation. For heavier loads or specific building codes, it's essential to consult with a structural engineer or refer to local building codes to ensure safety and compliance. Additionally, using engineered wood products may allow for longer spans.
To determine the number of 4x8 pavers in a square foot, you first need to calculate the area of one paver, which is 4x8 = 32 square inches. Since there are 144 square inches in a square foot, you divide 144 by 32 to get 4.5. Therefore, you can fit approximately 4.5 4x8 pavers in one square foot.
4x8=32
A 4x8 foot sheet of 1-inch thick foam typically weighs between 2 to 3 pounds per cubic foot, depending on the type of foam. Therefore, a 4x8 sheet, which has a volume of about 32 cubic feet, would weigh approximately 8 to 12 pounds. The exact weight can vary based on the foam's density and composition.
Technically Yes, but you'll need to check with your building inspector because there are codes regarding structure that vary from place to place, and the inspector isn't going to pass something based on my say so.The old rule of thumb was 1 inch for 1 foot, so a 12 foot span would require a 2 x 12.A 4 x 8 isn't equal to a 2 X 16, or even 2 2 X 8's, but it should do if the load isn't too great.I'm guessing you want to go with 8" stock because you've got some headroom issues. You'd be better off structurally with an LVL (Laminated Veneer Lumber) or OSB (Oriented strand Beam) or a truss, but these are kind of pricey.If you get in trouble see if they'll let you go with them on 12" centers.

A 30 foot circle covers about 707 square feet. 23 pieces would technically cover that. I'd get 30 of them so I wouldn't have to cut any of them.
A 4x8 foot sheet of 18mm MDO Plywood typically weighs around 80-85 pounds.
Pegboard panels typically weigh around 20-30 pounds per 4x8 foot panel, depending on the thickness and material used.
Should be able to squeeze it into a 4x8, 4x10. Draw it out using a scale of 1/4" = 1 foot before you start.
