Question

This section of guttering can hold up to 20 litres of rainwater. work out the length of guttering in metres

Answer 1

Answer:

Step-by-step explanation:

you need more detail of the cross-section, what is it's shape?

If I assume it's a half a circle, then the radius is 6 cm, and the area is ½πr²

that is A = ½π6² = 56.5 cm²

and volume is that x length, or V = 56.5L

20 L = 20000 mL = 20000 cm³

so we have

20000 = 56.5L

L = 354 cm

But if the cross-section is different, that will not be the answer.
