Imagine drawing a square on a piece of paper. Obviously, this drawing is in 2-D because although the picture has length and width, it has no height, or in other words, does not occupy space in the 3-D world.

However, the cube is in 3-D. It has all the properties of a three-dimensional object: it has length, it has width, and it has height. The cube occupies space throughout our world and is therefore a three-dimensional object.

Surface area is in 2-D. When we measure surface area, we do not measure thickness, or height. We only measure the length and width. Similarly, because the square has length and width but not height, it is used to measure surface area.

Volume, however, is in 3-D. When we measure volume, we also measure the space it occupies in our world. Similarly, the cube occupies space through our world. How could you draw a cube with a square when it has no thickness??? Therefore, we use squares to measure surface area and cubes for volume.

Squares cannot be used to measure a three-dimensional volume since they have only two dimensions. Squares are used to measure surface areas, such as the outer surface of a rectangular solid. Cubes are used to measure volume because they are the simplest geometric division of a three-dimensional space. For a rectangular solid, multiplying H x W x D literally tells you the number of cubes (of the given unit of measurement) that can be contained within that space.

Yes Volume: Is the amount it takes to build it. Surface Area: Is how much is on the surface.

You cannot calculate standard deviation for objects such as concrete cubes - you can only calculate standard deviation for some measure - such as side length, surface area, volume, mass, alkalinity or some other measure.

A cube with 1 cm sides has a surface area of 6 cm2 and a volume of 1 cm3.

Cubes of squares or squares of cubes, like 1, 64 and 729.

surface area is the total outer area of a figure (I.E. a cubes surface area can be calculated by adding the area of its 4 squares)
