Question

a rain gutter is 24 feet long, 4 inches in height, 3 inches at base and 6 inches at top. how many gallons of water will it hold?

Answer 1

Answer:1.8701

Explanation:

Area (A) of trapezium as marked is =
`(1)/(2)`
`\left ( sum\ of\ parallel\ sides\right )* height`

A=
`(1)/(2)`
`\left ( 3+6\right )* 4`

A=18
`in^2`

Now for Volume we have to multiply by length because area is same across the length.

volume(v)=
`A* length`

Volume(v)=
`18* 24`

Volume(v)=432
`in^3`

Volume(v)=1.8701 gallon
