Solve for x.

x^3=8/125

enter your answer in the box as a fraction in simplest form.

First you divide 8 by 125, with a new equation of:
x^3=0.064
You then take the cube root of 0.064, which happens to be 0.4
x=0.4
To make sure you can do 0.4*0.4*0.4.

So we know that we only have 450 people coming to the event.

When the guests arrive, will everybody have a place to sit?
Chairs: 0.6 * 600 = 360, not enough since there are still 90 people standing.

Will there be enough meals?
Meals: 0.6 * 600 = 360, not enough since there are 90 people who doesn't have meals.

Enough dessert?
Deserts: 0.625 * 600 = 375 , not enough since 75 people left with no desserts.
