V= a x a x a verses the Volume of a box which equals
lenght x height x width

Now we take the 3rd root of 68.921 by 3✔ ️because all sides are equal on a cube. We have 4.10 ft.

Check:
4.10 ft x 4.10 ft =
16.81 ft^2

16.81 ft^2 x 4.10 ft = 68.921 ft^3

If it takes 4 men 6 hours to repair a road, How long will it take 3 men to do the job if they work at the same rate ?

Answers

Answer:

8 Hours

Step-by-step explanation:

Let the the length of the road x

It takes 4 men 6 hours to repair a road and they work at the same rate.

So, each one will repair 0.25x

And the rate to repair the road will be 6 hour per 0.25x.

rate = $(6 \ hours)/(0.25\ x)$

Now, if 3 men will do the job

each one of them will repair (1/3) x with the same previous rate

∴ $(time)/(1/3 \ x) = (6 \ hours)/(0.25 \ x) \nTime = (1)/(3) x * (6 \ hours)/(0.25 \ x) = (2)/(0.25) =8$

So, The 3 men will do the job at 8 hours.
