Number of Components per Row= Bed Length divided by Component Length (Round up) <br />I I ft + I I ft= I I components/row <br />D. Actual Bed Length= Number of Components/row X Component Length: <br />I I components X I 1ft = I ltt <br />E. Number of Rows= Bed Width divided by Component Width (Round up) <br />I I ft+ I I ft= I I rows Adjust width so this is an whole number. <br />F. Total Number of Components = Number of Components per Row X Number of Rows <br />I I X I I = I I components <br />6. MOUND SIZING <br />A.
