Brainliest me please if I'm right

Answer 2

Answer:

5916

step by step :-

The surface area of a cuboid can be defined as the total amount of the area of all its surfaces. Because a cuboid is a three-dimensional solid shape, its surface area is determined by its length, width, and height.

Here, l=15,b=6,h=4

.

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

⇒2(15×6+6×4+15×4)

⇒348cm2

Here, the cost of painting is Rs 17 per m2

.

Now, total cost =348 ×17=5916

.

Hence, the total cost to be paid is Rs. 5916
