The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 1800 cubic centimeters when the pressure is 250 millimeters of mercury (mm Hg), find the volume when the pressure is 450 mm Hg.

The cross-sectional areas of a right triangular prism and a right cylinder are congruent. the right triangular prism has a height of 6 units, and the right cylinder has a height of 6 units. which conclusion can be made from the given information? the volume of the triangular prism is half the volume of the cylinder. the volume of the triangular prism is twice the volume of the cylinder. the volume of the triangular prism is equal to the volume of the cylinder. the volume of the triangular prism is not equal to the volume of the cylinder.
