Solution

Given the side of the cube $= 6$ m
TSA of the cube $= 6 \times {(s i d e)}^{2} = 6 {(6)}^{2} = 6 \times 36 = 216 m^{2}$
The cost of painting is Rs. $2$ per $100 {c m}^{2}$
$∴$ cost of $1 {c m}^{2} = \frac{2}{100} =$ Rs. $0.02$
we know that $1 m^{2} = 10000 {c m}^{2}$
$216 m^{2} = 2160000 {c m}^{2}$
Hence total cost of painting the cube $= 2160000 \times 0.02 =$ Rs. $43200$
