What kind of figure?
If you think about rectacangular prism:
V=a*b*c
a,b,c sides of prism
a=5 1/2= 2*5/2 +1/2 =10/2 + 1/2 = 11/2
b=3 1/4= 3*4/3 + 1/4=12/4 +1/4 =13/4
143=11/2 * 13/4 *c
143=143/8 * c Multiply with 8
143*8= 143*c Divide with 143
8=c
c=8 ft
V=a*b*c=11/2 * 13/4 * 8= 11*13*8 / 2*4 =
1144 / 8 = 143 ft^3
