The length of the cuboid is 15 cm.
- Let the length of the cuboid be l cm.
Breadth of the cuboid is 10 cm
Height of the cuboid is 20 cm.
Total surface area of the cuboid is 1300 cm²
- Formula to find the surface area of the cuboid is 2(lb + bh + hl).
1300 = 2 (10l + 200 + 20l)
650 = 30l + 200
450 = 30l
l = 15 cm
