Find the cost of painting a cuboid container of length 4 m, width 3.5 m and height of 6 m at the rate of Rs 43.78 per square metre?
Explanation
To find the cost of painting, we need to calculate the surface area of the cuboid:
Surface Area = 2(lw + lh + wh)
= 2(43.5 + 46 + 3.5*6)
= 2(14 + 24 + 21)
= 2 * 59
= 118 square meters
Now, cost of painting:
Cost = Surface Area * Rate
= 118 * 43.78
= 5166.04
