l = 30 cm h = 10 cm b = ?
Total surface area = 2 ( l b + bh + h l) = 608 m² (not cm² ??)
30 b + 10 b + 30*10 cm² = 608 / 2 * 10⁴ cm² units conversion
40 b = 3040, 000 - 300
b = 75992.5 cm = 759.925 meters
very long slab... ???
============
If the total surface area is 608 cm² not m², then
40 b = 608/2 - 300 = 4 cm²
b = 0.1 cm = 1 mm
