**cube**canberepresented as , since a

**cube**has six sides and thesurfacearea of each side is represented by its length multiplied byitswidth, which for a

**cube**is , since all of its

**edges**are the same length. So, one

**edge**of this

**cube**is inlength.

In respect to this, what is edge length of cube?

Recall that a **cube** has all **edges** thesame**length** (See **Cube** definition). The volume ofa**cube** is found by multiplying the **length** ofany**edge** by itself twice. So if the **length** ofan**edge** is 4, the volume is 4 x 4 x 4 = 64. Or as aformula:volume = s^{3}.

**calculate the volume**of a

**pyramid**witharectangular base,

**find**the length and width of the base,thenmultiple those numbers together to

**determine**the areaof thebase. Next, multiply the area of the base by the height ofthe

**pyramid**. Take that result and divide it by 3to

**calculate**the

**pyramid's volume**!

One may also ask, how do you find the edge length of a cube with mass and density?

**Density** Vs. This means that it has a **length**, widthandheight. Like a square, all sides of a **cube** bydefinitionhave the same value, so once you **know the length**of one**edge**, you also **know the length** of theother**edges**. Using this idea, you can **calculate**the**mass** of a **cube** with the formula for **Density**=**mass** ÷ volume.

Explanation: A **cube** has 6 faces. The**area**of each face is found by squaring the length of theside. Multiplythe **area** of one face by the number of faces toget the**total surface area** of the **cube**.
