Find total surface area (18*12)*2+ (18*8)*2+ (12*8)*2= 192 +288 432+288+192= 912
then subtract surface area of doors
(3*7)2=42 then subtract windows 3*5(3)=45 then subtract the floor 18*12=216
912-42-45-216= 609 sq ft he should only need 2 and a small portion of a third to paint your room i believe what his math must have been was 18*12*8=1728 then subtract -42-45-216 for the floor windows and doors to get 1425 and even then he underestimates with his inaccurate figures
so first 609 sq ft he should only need 2 and a small portion of a third to paint your room and 2 get a new painter bcus this guy cant math hope i helped if so give brainliest answer-J (:

Answer:
the sum of -4.82 and 4.35 = -0.47
so a is correct
the product of -4.82 and 4.35 = -20.967
so b is incorrect
the quotient of -4.82 and -4.35 is 1.10804597701
the quotient of 4.82 and 4.35 is 1.10804597701
so c is correct
if we subtract 4.35 from -4.82 we get -9.17
so d is incorrect
Hope This Helps!!!
