Why did you choose the answer you chose?

So... what does this have to do with volume?

Well...

We need to learn the difference between volume and surface area.

Volume is:

THE AMOUNT OF SPACE INSIDE OF AN OBJECT.

NOW... LET'S GET BACK TO THE PANTS.

Soo.. How do you calculate volume?

• Volume of a prism = Area of the base (B) x height of the prism (h)

• For a rectangular prism, that means Volume = l x w x h

• Let's see an example:

Example: Find the Volume of the Prism

• Volume = Bh

• Volume = l x w x h

• Volume = 3 x 2 x 3

• Volume = 18 units³
