Question

hiset practice test questions the wood floor of a community recreation center is in the shape of a square that is 200 feet by 200 feet. if directions on a bottle of floor wax indicate that $\frac{1}{2}$ of a bottle will cover approximately 2,000 square feet, about how many full bottles of floor wax are needed to wax the wood floor? a. 5 b. 10 c. 20 d. 40 e. 100

Explanation:

Step1: Calculate floor area

The floor is a square with side - length $s = 200$ feet. The area of a square is $A=s^2$. So, $A = 200\times200=40000$ square feet.

Step2: Determine area covered by one bottle

If $\frac{1}{2}$ of a bottle covers 2000 square feet, then one bottle covers $2\times2000 = 4000$ square feet.

Step3: Calculate number of bottles

Let $n$ be the number of bottles. We use the formula $n=\frac{A}{area\ per\ bottle}$. So, $n=\frac{40000}{4000}=10$.

Answer:

B. 10
