A plumber needs to replace 20 feet of copper piping . When he gets to the supply store , the lengths are given in meters . How many meters of piping does he need to purchase ?

6.096 m

Step-by-step explanation:

We need to convert 20 ft into meters.

We can use these conversions:

1 ft = 12 in.

1 in. = 2.54 cm

100 cm = 1 m

20 ft * (12 in.)/(1 ft) * (2.54 cm)/(1 in.) * (1 m)/(100 cm) = 6.096 m

6.096 m

7 meters.

Step-by-step explanation:

I say 7 meters, because a meter is around 3 feet so to get to 20 feet you would buy 7 meters of copper piping to get a total of 21 feet which is close to 20 feet.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
