570mm in 57cm
57cm X 54cm X 15 cm equals 7,156 square inches.
The internal volume will be the internal diameter times pi times the length.The internal diameter is the outside diameter (57cm) minus twice the wall thickness (2 * 9 = 18cm) = 57 - 18 = 3939 pi * 100 = 12252 cubic centimeters or more than 12 liters
57 centimeters is 1 foot 10.44 inches.
