Question

Find the cost of painting a wooden box which is in the shape of a cube of side 11 cm at the rate of 50 paise per square cm

Answer 1

Answer:

Rs.363

Step-by-step explanation:

Length of side of cube = 11 cm

We are required to find the total area of cube that need to be painted

So, we are supposed to find the total surface area of cube

Total surface area of cube = $6x^{2}$

where x is the side

So, Area = $6(11)^{2}$

               = $726cm^2$

Now cost of painting 1 square cm = 50 paise

So, cost of painting 726 square cm = 726*50 =36300 paise = Rs.363
