Answer
The inside area can be calculated by taking the outside dimensions and subtracting the wall thickness:
Inside Length = 7000 mm - (2 x 220 mm) = 6560 mm
Inside Width = 4000 mm - (2 x 220 mm) = 3560 mm
Inside Area = (6560 mm x 3560 mm) / 1000000 = 23.36 m²
(Rounding off to two decimal places gives 23.35 m²).
