Volume of Triangular Prisms
A triangular prism is exactly half a rectangular prism — the triangle base is half the rectangle. Students see that the prism formula works for any prism: find the base area, multiply by height. This generalizes beautifully and sets up the cylinder volume formula in Grade 7.

Key ideas
Calculate the area of a triangle. Apply the formula V = base area × height to triangular prisms. Distinguish between triangular prisms and other prisms. Solve volume problems in real-world contexts.
Putting it together
Apply these ideas through hands-on activities, guided practice, and real-world problems.
