Step-by-step explanation:
The answer is 3.16 ft
The surface area (SA) of the rectangular prism is:
SA = 2lw + 2ld + 2wd
However, the pool is without the top side, so the area of the top side should be excluded from the surface area of the pool. The surface area of the rectangular pool is:
SA = lw + 2ld + 2wd
We know:
SA = 210 ft²
l = 9 ft
w = 10 ft
d = ?
210 = 9 * 10 + 2 * 9 * d + 2 * 10 * d
210 = 90 + 18d + 20d
210 - 90 = 38d
120 = 38d
d = 120/38
d = 3.16 ft
Answer:quit
Step-by-step explanation:
Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
