<span>Curtis wants to build a model building.
The building height is 180 meter tall.
Now, the model building she wants to build is equals to 1.5cm on each 3.5
meters
Let’s find how tall Curtis’ building model is:
=> 180 meter / 3.5 meter
=> 51.429 meter
Now, let’s multiply this 1 by 1.5 cm
=> 51.429 x 1.5 cm
=> 77.143 centimeters
Round to the nearest tenths
=> 77.1 centimeter tall => the height of Curtis’ Model Building

Both sides of one wall would be 90 square feet. 2 coats of paint for both sides would be 180 square feet. There are 5 walls, so the square feet to be painted is 5(180)=900
So, Peter needs 900/x gallons of paint.
