{[3(30*45)]/1.96}*25 = cost of painting the building on the outside. Use your calculator.
And the top is an equilateral triangle, each side is 30m:
A = (sqrt3/4)*a^2
A = [sqrt(3/4)]*30^2
A = 0.433*900 = 389.7 meters is the area of the triangular rooftop.
(389.7*10.764)*200 is the cost of fixing the glass on the roof. Use your calculator.
