How many blocks with dimensions of One-fourth times 1 times 1 are needed to fill the gap in the prism? A prism has a length of 3 and three-fourths, height of 3, and width of 2. 18 blocks are inside of the prism. 6 12 18 24

Its radius = 16  
Volume = (4/3)*pi*(16)^3 =  16384 pi
                                               
                                                 3

The sphere has a diameter of 16*2  = 32

The radius length is one half the diameter

Correct choices are No. 3, 4 and 5
