The volume of a rectangle prism is 100 cubic inches. which of the alternatives is it's greatest possible length?

The complete question in the attached figure

we know that

[volume of a rectangular prism]=L*W*H

of the alternatives presented the greatest is 100
100>10
100>20
100>60
100>50

V=L*W*H
for V=100 in³  and L=100 in
100 in³=100*W*H----------> W*H=1

so that the longest length is 100 the product of the width by the height must be equal to 1

the answer is
the option A) 100

A= r2 × 3.14 7x7 ↓ ↓ 49 × 3.14 = 153.86 → 153.9
