Surface area of the cuboid is the sum of the area of all the sides. The surface area of the box is 912 yards².
What is the surface area of the cuboid?
The surface area of the cuboid is the sum of the area of all 6 sides of the cuboid.
The surface area of the cuboid
= 2[(Length x breadth)+(Length x height)+(height x breadth)]
As it is given to us that the box is rectangular, therefore, the actual shape of the box is cuboid. And for a cuboid, the surface area is given as,
The surface area of the cuboid
= 2[(Length x breadth)+(Length x height)+(height x breadth)]
Also, the length, breadth, and height of the cuboid is 12 yards, 8 yards, and 18 yards, therefore,
The surface area of the box = 2[(12 x 8)+(12 x 18)+(8 x 18)]
= 2[(96)+(216)+(144)]
= 912 yards²
hence, the surface area of the box is 912 yards².
