Challenge The Travers are adding a new room to their house. The room will be a cube with volume 8,000 ft. They are going to put in hardwood floors, and the contractor charges $5 per square foot. How much will the hardwood floors cost? The hardwood floors will cost $​

$2000

Step-by-step explanation:

Take the cube root of 8000 (the volume) to get the side length which is 20 feet.

So it's a square room 20 by 20, or 400 square feet.

400sq ft times $5 per sq ft = $2000

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
