The surface area of a rectangular prism is always:
A=2(xy+xz+yz), where x, y, and z are the three dimensions of the prism.
A=2(50*90+50*3.5+90*3.5)
A=2(4500+175+315)
A=2(4990)
A=9980 mm^2
I don’t see an attachment for a diagram
16/2=8
we need 8 times more flowers
8x8,000=64,000
64 thousand flowers
Hope that helps)
