Question

Find the surface area of the building - (not including what is on the ground, as if we were going to paint it)

Answer 1

Answer:

204.4m

Step-by-step explanation:

formula for SA of a rectangle is 2lw+2lh+2hw

so it would be 2(6x5) +2(6x3)+2(5x3)=126m

formula for SA of a triangle is bh+2ls+lb

so it would be 5x2+2(6x3.2)+6x5=78.4m

then add 78.4+126=204.4m
