Question

The surface area of a cuboid is 758 cm². Its length and breadth are 14
and 11 cm respectively. Find its height.
in 11. find the volume of water th​

Answer 1

Answer:

height = 9cms

Step-by-step explanation:

Surface Area of cuboid = 2(lb+bh+hl)

Surface Area of the cuboid = 758cm² (given)

Length = 14cm

Breadth = 11cm

Height = ?cm

ATQ

=> 2(lb + bh + hl) = 758

=> lb + bh + hl = 758/2

=> lb + bh + hl = 379

=> 14 × 11 + 11h + 14h = 379

=> 154 + 25 = 379

=> 25h = 379-154

=> 25h = 225

=> h = 225/25

=> h = 45/5

=> h = 9cms
