How many cubic yards are in a 12 x 2 x 5 foot form?

Answer 1

Assuming that the form is a parallelepiped, its volume in cubic feet is the product of its three dimensions in feet: 12 X 2 X 5 = 120 cubic feet. There are 27 cubic feet per cubic yard; therefore, the volume in cubic yards is 120/27 = 4 cubic yards, to the justified number of significant digits. If the dimensions given are considered exact, the answer is 4 and four-ninths cubic yards.
