The pillars and the pyramids in the stadium gate means that we have to calculate the area of the items that make up the gate one after the other. At the end of the calculation, the calculated areas are then added up.
The total cost of painting is Rs.21344
First, we calculate the area of 1 side of 1 pillar using:
Where
--- Height of the pillar
--- Base of the pillar
So:
The area of the 4 sides of the pillar is:
--- i.e. 4 multiplied by the area of 1 side
The area of the 2 pillars is:
--- i.e. 2 multiplied by the area if 1
Because one part of the pyramid won't be visible, we calculate the area of the pyramid using:
Where:
-- the height
--- the base of the pillar is the length and width of the pyramid.
So, we have:
For the two pyramids, the area is:
-- 2 multiplied by area of 1
So, the total area to be painted is:
--- the sum of the area of the pillars and the pyramids
The unit cost of paint is:
Rate = Rs80 per sq.ft
The total cost of painting is:
