surface area of the cuboid are 18 cm and 3384 cm” respectively. Find its length and breadth.

with explaination​

Answer 1

Answer:

L = 5 cm, b = 2 cm and h = 4 cm.

As we know,

Total surface area of the cuboid = 2(lb + bh + hl)

Total surface area of the cuboid = 2(5 × 2 + 2 × 4 + 4 × 5) = 2 (10 + 8 + 20) = 2 × 38 = 76 cm2
