Answer 1

Answer:

2) 12,000 ft²

3) 30 gallons.

Step-by-step explanation:

2) 1. You can calculate the lateral surface area of the exterior walls of the warehouse by applying the formula shown below:

$LA=h(2l+2w)$

Where h is the height, l is the lenght and w is the width.

2. Substitute values and you obtain that the lateral area is:

$LA=20ft[(2*200ft)+(2*100ft)]$

$LA=12,000ft^{2}$

3) You know that 1 gallon of paint covers 400 ft², therefore for 12,000 ft² are needed the following number of gallons (which is represented by x):

$x=\frac{(1gallon)(12,000ft^{2})}{400ft^{2}}=30gallons$
