Ascale model of an office building is 3' x 2' x 5' (length, width, height). if the actual building has a length of 45 feet, what is the volume of the actual building?

Model - 3' x 2' x 5' (length, Width, Height) 

45/3=15 

2*15=30

5*15=75 

Actual building - 45ft x 30ft x 75ft (Length, Width, Height) 
 
Volume - L*W*H 

45*30*75=101,250

The answer to your question is 101,250
