I will mark you as a brainliest ​

Answer 1

Answer:

It is given that

Surface area of cuboid =758 cm

2

The dimension of cuboid are

Length =14cm

Breadth =11cm

Consider h as the height of cuboid

We know that

Surface area of cuboid =2(1b+bh+1h)

By substituting the values

758=2(14×11+11×h+14×h)

On further calculation

758=2(154+11h+14h)

So we get

758=2(154+25h)

By multiplication

758=308+50h

It can be written as

50h=758−308

By subtraction

50h−450

By division

h=9cm
