Answer:

9.85 currency per m^2

( you haven't specified currency that needs to be used)

Step-by-step explanation:

Length = 6.5

breadth = 5

height = 3

For 4 walls we need their lateral surface area.

Lateral surface area of cuboid = 2h(l+b)

                                                   = 2 x 3 (6.5 + 5)

                                                   = 6 x 11.5

                                                   = 69cm^2

As cost of painting 1 m^2 = 7 currency

Cost of panting 69m^2 of area = 69/7 = 9.85 currency

( you haven't specified currency that needs to be used)
