Question

please give me the answer

Answer 1

I hope this will help you.


As 5cubes are placed together,

It will make a cuboid of length =5*6=30,breadth =6, height=6

SA of cuboid =2(lb+bh+hl)

SA= 2(30*6+6*6+6*30)

SA =2(180+180+36)

SA=396*2

SA=792m²

Cost of painting =792*300=rs237600

Answer 2

when 5 cubes placed together it forms a cuboid
the length of the cuboid =5*6
=30cm
the breadth of cuboid =6cm
the height of the cuboid =6cm
to paint the cuboid we need to find total surface area
T. S. A of cuboid =2(lb+bh+lh)
=2(30*6+6*6+6*30)
=2(180+36+180)
=2(396)
=792
total cost of painting cuboid =300*792
=237600
