Answer:
1860cm or 18.6m
Step-by-step explanation:
first convert metre into centimeters for ease
1m=100cm
yellow wire=6m×100= 600cm + 20cm= 620cm
red wire=4m × 100 = 400cm + 20cm=420cm
black wire = 8m × 100=800cm + 20cm=820cm
add all
total length of all wires =620+420+820=1860cm
convert to metre
1860/100=18m60cm or 18.6m
