In reference to your Kenmore Washer, Model # 110.28802890
To calculate the capacity (volume) of the tub, you multiply the area by the height. For example if your washer has a tub radius of 10 inches and the height is 14 inches, you would use the mathematical equation below.
Area is pi x r-squared = 3.1416 x 10-squared = 3.1416 x 100 = 314.16.
Volume = 314.16 x 14 = 4398.24 cubic inches.
There are 1728 cubic inches per cubic foot, so you divide 4398.24 by 1728 = 2.5452777 cubic feet.
So the cubic feet of capacity of your washer would be 2.5.feet
