So once you find the area of one side of the rectangle, multiply it by four. Then find the area of the sides. |dw:1435756930736:dw|
So there are four x's that should be the same side of this is a rectangle. How would you solve for the y's.
I'm not trying to solve for y's i just wanted to know how to find the surface area of a 3D shape. also what if it didn't have a top?
The surface area of something is every single side. since it's a 3D shape, it has... 6 faces. Hence why you need to find out what "y" equals in order to find the surface area of something. If it didn't have the top I don't think it'd be considered a 3D shape.
Yes, but they have bottoms... in which case, you'd still have to find the surface area of the bottom of the pail.
but so does the rectangular prism! it has a bottom and a top
|dw:1435764803251:dw| How many faces does this have?
7 the 6 front sides and the inside
6 outsides not front sides
No, we don't care about the inside. Pick up a box, a good ol' cardboard box. How many faces will that have when you prop it up?
