The surface area of a cuboid is Its length and breadth are 14 cm and 11 cm respectively. Find its height.
Given,
Surface area of cuboid = 758 cm2
Length of cuboid = 14 cm
Breadth of cuboid = 11 cm
Let height of cuboid = h cm
Total surface area of cuboid = 2 (lb + bh + hl)
= 758 = 2 (14 × 11 + 11h + 14h)
= 154 + 25h =
= 25h = 379 – 154 = 225
= h =
Height of cuboid = 9 meter.
