To determine the maximum occupancy of the chute, the fire department requires chute designers to allow 0.75 feet^2 for each person in the chute.

Calculate all of the sq ft of the chute...

the top rectangle   8 * 12 = 96 ft^2

the rectangle below this one = 8 x 10 = 80 ft^2

and the two side triangles     2  *  1/2 x 10 x 6.5 = 65 ft^2

 

Added all together = 241 ft^2

241 ft^2  / .75 ft^2/person = 321.33 ~~~~321 persons
