(a) For the minimum (43 cm) case, 9 cubit converts as follows:

(9 cubit)



0.43 m

1 cubit



= 3.9 m .

Andfor the maximum (43 cm) case we obtain

(9 cubit)



0.53 m

1 cubit



= 4.8 m .

(b) Similarly, with 0.43 m

430 mm and0.53 m 530 mm, we find3.9×10

mm and4.8

×10

3

mm,

respectively.

(c) We can convert length anddiameter first andthen compute the volume, or first compute the volume

andthen convert. We proceedusing the latter approach (where d is diameter and  is length).

Similarly, with 0.43 m replacedby 0.53 m, we obtain V
