Hi everyone. On Friday our test was canceled so we learned about finding the surface area of a Rectangular prism, which has length, width, as well as height.

Now. Here is a rectangular Prism, with some random numbers. Today the unit I am going to use is centimeters.

The length is 2 cm, the width is 5cm, and the height is 3 cm.

Formula: 2(lw)+2(lh)+2(wh)

2(2cm x 5cm) = 20, 2(2cm x 3cm) = 12, 2(5cm x 3cm) = 30cm

20+12+30 = 62

Our surface area is 62 cm2

If my answer is wrong, please correct me. Basically, all I did was follow the formula. Thanks for reading. And don't forget to study for the test we have on symmetry tomorrow.

Do the scribepost earlier next time, it helps.

ReplyDeleteas harvey said make the post earlier and also ur diagram with the rectangular prism the numbers i cant see but nice explianation with ur formula but make ur post alittle better so it could be a real scribe
