Math Question, kinda have me confused?

I did math like this before,
but i recently went back to school and forgot alot of the math i did,

so question is:
To maintain proper humidity, an attic should have 8.95 x 10^2 cm2 of ventilation for every
27.0 m2 of floor area. How much ventilation is needed for your building?

did the first part of it.. 18,609.02m2 floor area

how would you do this?,

also i got 0.0895 m2 for 8.95 x 10^2 cm2


patricia e



18609.02 /27 = 689.22

689.22 X 8.95 X 10^2 = 6168.52 X 10^2 cm^2 ANSWER


ohhh very easy . first divide the floor area with 27 m2 and then multiply the ans that was obtained by division with 8.95 x 10^2 cm2
