Answer:

five cubes are placed side by side together as shown in the figure all cube have length of Edge as to CM the block the created is to be painted on all sides find the cost of pointing at rupees 20 per CM square

Answer 2

Answer: The cost of painting is ₹1760 if edge is 2cm

Step-by-step explanation:

First we have to count the sides that need to be painted so in first cube 5 sides in second, third, fourth 4 sides and in fifth 5 sides

So total sides to be painted

5+4+4+4+5=22 sides

Now, area of each surface =2*2cm² =4cm² ( In such questions if edge is 5 so we do 5*5 and if 4 so 4*4 and vice versa)

So, total area of painting= No.of sides*Area of each surface

22*4=88cm²

Now cost of painting=20cm²

So, Cost= 88*20= ₹1760

And that's our final ans
