Answer:

3.5 inch^3

Step-by-step explanation:

Volume of cube: V = s^2,

where V = volume, and s = length of side or edge.

The volume of the prism is the same as the volume of 28 cubes with edge length of 1/2 inch. To find the volume of the prism, find the volume of one cube and multiply by 28.

volume of prism = 28 * volume of cube

volume of prism = 28 * (1/2 inch)^3

volume of prism = 28 * 1/8 inch^3

volume of prism = 3.5 inch^3

A ferry traveled 1 6 6 1 ​ start fraction, 1, divided by, 6, end fraction of the distance between two ports in 3 7 7 3 ​ start f
docker41 [41]

Answer:

\frac{7}{18} of the distance

Step-by-step explanation:

We know that a ferry traveled \frac{1}{6} of the distance between two ports in \frac{3}{7} hours.

In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :

The rate of the ferry is the same at any time.

The ferry will travel \frac{1}{6} of the distance in \frac{3}{7} hours.

If we divide each fraction by 3 ⇒

\frac{\frac{1}{6}}{3}=\frac{1}{18} and \frac{\frac{3}{7}}{3}=\frac{1}{7}

We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :

The ferry will travel \frac{1}{18} of the distance in \frac{1}{7} hours.

Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒

(\frac{1}{18}).7=\frac{7}{18} and (\frac{1}{7}).7=1

We found out that the ferry will travel \frac{7}{18} of the distance in 1 hour.
