Answer:
2 pieces
Step-by-step explanation:
You want to know the number of pieces 420 mm × 594 mm can be cut from a sheet that is 600 mm × 1000 mm.
Dimensions
Comparing the dimensions, we see that both dimensions of an A2 piece (420 mm, 594 mm) are shorter than the short dimension of the given sheet. However, the long dimension of the A2 piece will not fit twice in the long dimension of the cast sheet.
2 pieces of size A2 can be cut from the cast sheet.

Additional comment
The pieces must be arranged so the long dimension of the A2 piece takes up most of the short dimension of the cast sheet.
The number can also be figured by comparing the areas, as in the attachment. The cast sheet has an area of about 2.4 times the area of an A2 piece.
