Answer:

Volume A = Volume B ⇒ last answer

Explanation:

* Lets explain how to solve the problem

- The volume of any prism = The area of the cross section × its length

- Prism A is a rectangular prism

∴ Its cross section is a rectangle with dimensions 6 units and 4 units

∵ The area of the rectangle = length × width

∴ The area of the cross section = 6 × 4 = 24 units²

∵ Its volume = The area of the cross section × its length

∵ Its length = 7.22 units

∴ Its volume = 24 × 7.22 = 173.28 units³

- Prism B is a triangular prism

∴ Its cross section is a right triangle with base 8 units and height

6 units

∵ The area of the triangle = 1/2 × base × height

∴ The area of the cross section = 1/2 × 8 × 6 = 24 units²

∵ The its volume = The area of the cross section × its length

∵ Its length = 7.22 units

∴ Its volume = 24 × 7.22 = 173.28 units³

- The volume of the rectangular prism equals the volume of the

triangular prism

Volume A = Volume B
