Volume of a prism = cross-sectional area x length (or its height, if it's upright!). Here the cross-sectional area is not a rectangle (9 x 5 = 45), but a triangle ( 9 x 5 / 2 = 22.5), making the volume 22.5 x 10 = 225 (and not 45 x 10 = 450). Hope this helps!

Thank you good sir for this video! :D
You are most welcome, Nerd-Y Boi!
At 5:11 just to correct you accidentally mentioned 100cm cubed = 1L 🙂
Doh! You are quite right. Thanks for the correction!
My teacher told me that the volume of any prism is base area * height
So shouldn’t it be 450?
