In this video, explore volumes and surface areas of cylinders and boxes.
 [Instructor] So the GMAT will also occasionally…test shapes that are three dimensional…like cubes, boxes and cylinders.…So in this video we'll talk about finding…the surface area and volumes of these particular shapes.…So let's start with a cube.…So if I draw a 3D cube,…the nice thing about a cube…is that each side is the same…as every other side.…So if we need to get the volume of a cube…it's just one of the sides cubed.…
So that's our volume of a cube.…Now if we had a box,…I'll just draw a box like this,…the volume is length times width times height…is the volume of a box.…So let's say that this would be the length,…this would be the width and this would be the height,…multiply those three things together…and boom, you've got your volume.…
Now let's talk about the surface area…of these shapes as well.…So if you remember that to get the area of a square,…you square the side length of it, so it would just be,…let's say we had this cube over here,…I'll redraw it here.…Let's say that one of the sides had a length of three.…
