AnswerThe total surface area of the cuboid is

112m²We are given ,

The length is 2 times the breadth

And again ,

The length is 4 times the height

Also we are given ,

Therefore , the length of the cuboid is

8mThus the breadth and height is

Now , calculating the surface area :

Ther , required surface area of the cuboid is

112m²• The length of cuboid is two times it’s breadth.

• The length of cuboid is four times it’s height.

• Volume of cuboid = 64m³

• The total surface area of the cuboid

Let the length of the cuboid be x

Given length is 2 times its breadth

Given, length is 4 times its height

Volume of cuboid = l × b × h = 64cm³

Now;

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

Therefore:-
