Question 120309
If the sand covers 8.1m^2, this means the area of the base is {{{A=8.1}}}


So the volume {{{V=(1/3)Ah}}} Start with the given formula




{{{5.4=(1/3)(8.1)h}}} Plug in the given volume {{{V=5.4}}} and the area {{{A=8.1}}}



{{{5.4=(2.7)h}}} Multiply



{{{5.4/2.7=h}}} Divide both sides by 2.7 to isolate h



{{{2=h}}} Divide




So our answer is {{{h=2}}} which means the height is 2 meters
