Surface Area per Square Foot @ 2" Deep
Each 1/8" HydroFoam™ Bead has .0735 Square Inches of Surface Area.
- HydroFoam™ Beads have an average diameter of 1/8".
- 1/8" = 0.125".
- The Diameter of each bead is 0.125"
- Radius = 1/2 the Diameter.
- The Radius of each bead is 0.0625" (0.125" ÷ 2 = 0.0625").
- Surface of a Sphere is calculated: 3 x Pi x radius squared.
- Pi = 3.14
- Surface area of each bead: 4 x 3.14 x (.0625" x .0625") = 0.049" square inches of surface area per bead.
- HydroFoam™ Beads are made from High Density Food Grade Styrofoam which has 50% more surface area than a smooth, hard surface.
- 0.049" x 1.5 = 0.0735" square inches of surface area per HydroFoam™ Bead.
There are 512 HydroFoam Beads per Square Inch
- 1/8" beads = 8 beads per inch.
- 8 beads long x 8 beads high x 8 beads long = 1 cubic inch of beads.
- 8x8x8 = 512 beads per cubic inch.
There are 884,736 HydroFoam™ Beads per Cubic Foot.
- 12" x 12" x 12" = 1 cubic foot.
- 12" x 12" x 12" = 1,728 cubic inches per cubic foot.
- 512 beads per cubic inch.
- 512 beads x 1,728 cubic inches = 884,736 beads per cubic foot.
HydroFoam™ Beads Have 451.584 Square Feet of Surface Area
Per Cubic Foot
- 884,736 beads x 0.0735 square inches of surface area per bead.
- 884,736 x 0.0735 = 65,028.096 square inches of surface area per cubic foot of beads.
- 144 square inches = 1 square foot.
- 65,028.096 square inches ÷ 144 square inches = 451.584 square feet.
HydroFoam™ Beads Have 75.264 Square Feet of Surface Area
per Square Foot @ 2" Deep
- SSA (Specific Surface Area) is commonly calculated at 1 square foot by 2" deep.
- 1 cubic foot ÷ 6 = 2" deep.
- 451.584 ÷ 6 = 75.264 square feet of surface area per square foot at 2" deep.
