The numbers below are for that 110 by 95 inch quilt, with 4 inches of overhang for the backing and batting, 2 1/2 inch binding strips, and ordinary 42 inch quilting cotton. Change the quilt in the card and they follow.
Materials for a 110 × 95 inch quilt
Four inches of overhang on the back and the batting. Binding is 2 1/2 inch strips. The top is not in this list, because a pieced top is not a rectangle.

The top is not a rectangle
A pieced king top is not "110 times 95, divided by the width of the fabric." Seams, sashing, and the way a block is cut all change the yardage, and a single number would be a guess wearing a precise face. Design the top, or follow a pattern that already counted the pieces. Quiltler's fabric calculator does that from the design itself.
People still want a shopping range. A simple king top is often somewhere around 9 to 12 yards in total, split across several fabrics, before backing and binding. Treat that as a budget for the shop, then replace it with the pattern's list or a design before you cut.
Wide backing earns its keep on a king
A king top at 110 by 95 inches needs a back about 118 by 103 with four inches of overhang. On ordinary 42 inch quilting cotton that is three panels and more than eight yards. One hundred eight inch wide backing covers the shorter dimension in a single panel, cutting the backing purchase to a little over three yards — still a large piece to handle, but far fewer seams.
