Question 57 need help
prisoha [69]
Okay so first we need to find the height ofn one hay barrel. To do this we must use the equations v= h×w×l

We already know 3 out of the 4 variables in the equations, in this case we are given the volume so we must work backwards.

The equation will look like this:
10 \frac{2}{3}    = h \times (1  \frac{1}{3} ) \times 4
First we must mulitpy 4 and 1 1/3 to get 16/3. The equation will now look like:
10 \frac{2}{3}  = h \times  \frac{16}{3}
Next divide 16/3 from h then from 10 2/3 to get :
2 = h
The height is 2ft. Finally multiply 2 by the number of hay barrels (8) placed upon each other becuase we're finding the height and you will get your answer of 16 ft in height.
