room is 18ft long, 14ft wide, 8ft high.

find the cost of carpeting the floor with carpet costing $5./ft2

18 * 14 = 252 square feet

252 * 5 = ?

1,650

there are 20 student in the class 12 of them are boys what percent of class is boys

12%

To find the cost of carpeting the floor, we need to calculate the area of the room and then multiply it by the cost of carpet per square foot.

Given:
Length of the room = 18 ft
Width of the room = 14 ft

To calculate the area of the room, we use the formula:
Area = Length × Width

Area = 18 ft × 14 ft
Area = 252 ft²

Now that we have the area of the room, we can calculate the cost of carpeting by multiplying it by the cost per square foot.
Given:
Cost of carpet per square foot = $5

Cost of carpeting = Area × Cost per square foot

Cost of carpeting = 252 ft² × $5/ft²
Cost of carpeting = $1,260

Therefore, the cost of carpeting the floor would be $1,260.
