We need to convert everything to a common unit, so let's convert the 18 inches into 1.5 feet.
Volume is length times width times height.
v= 132 x 2 x 1.5
v= 396 cubic feet
To convert to cubic yards, imagine a yard cube. It is 3 feet by 3 feet by 3 feet for a total of 27 cubic feet.
v1 = 396 cubic feet/27 cubic feet per yard
v1 = 14 2/3 cubic yards
Hi Paula:
A mathematical logic question.
You need to get all of the measurements in the same units.
- A cubic yard is 1 yard x 1 yard x 1 yard
- equals 3 ft x 3 ft x 3 ft
- equals 27 cubic feet,
so once you have the volume of the pipe in cubic feet, you divide by 27 to get the volume in cubic yards.
- Volume of a cylinder (the pipe) is the cross sectional area X length.
- Area equals Pi x r squared.
- equals 22/7 x 1 x 1
equals 3.14#####
times length (20)
equals 62.857### cubic feet volume
divide by 27 cubic feet
equals 2.328### cubic yards.
- The answer is always the easy part.
- what is important is knowing exactly what the question is, and
- determing what calculations are needed to get the answer.
Wasn't that better than if I'd just said 2 1/3 cubic yards?
Cheers
Imagine or draw a cubic yard. It has a length of 1 yard, a width of 1 yard, and a depth of 1 yard. Now each of these yards can be broken down into 3 feet, since there are 3 feet in a yard. Thus, a cubic yard has a length of 3 feet, a width of 3 feet, and a depth of 3 feet. We have 3 x 3 x 3 or 27 cubic feet in a cubic yard.
Next, take 2106 and divide by 27. The answer is 78 cubic yards.
What's the question? A yard is three feet, so three yards would be nine feet. Three yards is three times as long as three feet. Three yards is six feet or two yards longer than three feet.
