Find the unknown dimension width 5 1/2 ft 3 1/4 ft volume 143 ft3

Answer 1

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

Answer 2

One correction:

b=3 1/4= 3*4/4 + 1/4=12/4 +1/4 =13/4
