Question

Q14 plz slove this question

Answer 1

Given Dimensions are:

Length of a cuboid = 14 cm.

Breadth of a cuboid = 11 cm.

Surface area of cuboid = 758 cm^2.

Let the height be 'x' cm.

We know that Surface area of cuboid = 2(lb + bh + lh)

⇒ 758 = 2(14 * 11 + 11 * x + 14 * x)

⇒ 379 = 154 + 11x + 14x

⇒ 379 - 154 = 25x

⇒ 225 = 25x

⇒ x = 9.

Therefore, the height of cuboid = 9 cm.

Hope this helps!

Here's , Your Answer :-

=) Given ,
Surface Area of cuboid = 758 sq. cm

Length = 14 cm 

Breadth = 11 cm 

Height = ? cm 

Acc. to question .

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

Now , 2(lb+bh+hl) = 758

=) lb + bh + hl = 758/2

=) lb + bh + hl = 379

=) 14 x 11 + 11h + 14 h = 379

=) 154 + 25h = 379 

=) 25 h = 379 - 154
 
=) 25h = 225

=) h = 225/25 

=) h = 45/5

=) h = 9 cms. (ans.)
