**Everything You know about Rectangular Prisms**

**Surface area of A Rectangular Prism**

To figure this out you have to cut the box in half like so!

then you have to do a formula for each side!

For the Front and the Back of the Box you have to use this formula Hieght x Length = ??

For the Right side and the Left side of the box you have to use the formula Height x Width = ??

For the bottom and top you have to use the formula Length x Width = ??

then for each of them yuo multiply it by two and that is your answer

**Now that we know all of this lets give out the numbers Hieght is 10cm the Length is 5cm and the width is 2 cm.**

**so lets figure it out**

Font and Back side: h x L = 10cm x 5cm x 2 = 100cm

Right and left side: H x W = 10cm x 2cm x 2 = 400cm

Bottom and Top: L x W = 5cm x 2cm x 2 = 100cm

Now you add it all together to get the surface area 50cm+20cm+10cm= 80cm²

**Volume of a Rectangular prism**

**to find the volume you have to do length x width x hieght =**

**or you can do base x hieght = **

**so the measurments are length 3cm height 5cm width is 1cm **

**so L x W x H = 15 cm thirds**
