Volume Review: Prisms and Pyramids

Let's try a triangular prism.

Which formula should we use to find the volume?

Since it is a triangular prism, we should use V = Bh.

Before we find "B," let's identify the base.

Which shape is the base?

Since it is a triangular prism, the base is the triangle.

Now lets calculate "B" - the area of the base.

What is "B"?

B, the area of the base, is 6 sq cm.

Notice how it's filled into the formula. Now we just need to fill in the height of the prism.

What is the h?

Hint: what is the distance between the 2 bases?

B = 6, h = 11

so V = (6) (11)

Multiply to find the final answer.

What is the volume of the prism?

Now try this prism on your own!

Find the volume of the rectangular prism.

Now let's try a pyramid together!

Which formula should we use to find the volume of the rectangular pyramid?

Since it is a rectangular pyramid, we should use $$V=\frac{1}{3}Bh$$  .

Now let's find the area of the base (B).

What is B?

The area of the base (B) is 48 sq ft.

Which formula shows the whole volume formula filled in correctly?

Now that we've filled in the formula, calculate the final answer.

What is the volume of the rectangular pyramid?

Now try this pyramid on your own.
