Step-by-step explanation:

Volume cube

v = 18³

v = 5,832

Volume sphere

v = (4/3)π9³

v = 3,053.6280592893

Volume space

v = 5,832 - 3,053.6280592893

v = 2,778.3719407107

We know that

the scale is is 1/2 inch = 4 feet

using a graph tool
the approximate measurements in the drawing are
5 cm x 4 cm
convert to in
5/2.54--------> 1.97 in
4/2.54------> 1.57 in

convert drawing to actual
if 0.5 in---------> 4 ft
1.97in-------> X
X=1.97*4/0.5------> X=15.76 ft

if 0.5 in---------> 4 ft
1.57 in-------> X
X=1.57*4/0.5------> X=12.56 ft

the approximate area of Quinto's bedroom is 12.56*15.76=197.95 ft²

the answer is
the option C)192 ft²
