Question

The Roman cubitus is an ancient unit of measure equivalent to about 0.445 m. Convert the 1.95-m height of a basketball forward to cubiti. HINT Use the conversion factor 1 cubitus = 0.445 m. In the conversion factor 1 cubitus = 0.445 m, the term "1 cubitus" is considered to be exact so that it never limits the number of significant figures reported in the answer. cubiti

Answer 1

Answer:

4.382 cubiti

Step-by-step explanation:

That's a simple exercise of cross-multiplication:

$\frac{x}{1.95}  = \frac{1}{0.445}$

x being the measure in cubitus we're looking for. We can isolate it:

x = (1.95 m * 1 ) / (0.445 m/cubitus) = 4.382 cubiti

1.95 m = 4.382 cubiti

Which totally makes sense... since a cubitus is roughly half a meter long... and the basketball is 2 meters high... so there are roughly 4 cubiti in 2 meters.
