Find the volume of a cube if an edge has length 2r st units.Volume =cubic unitsQuestion Help: Message instructorCheck Answer

Sagot :

You have a cube with side 2 rst units.

In order to calculate the volume of the given cube, you use the following formula:

V = a³

where a is the length of cube sides.

By replacing the value of a into V formula you obtain:

V = (2 srt)³ units³

V = 8 r³s³t³

where you have used tha fact 2³=8 and that variables r,s and t power to 3 are equal to r³s³t³.

Hence, the volume of the given cube is V = 8 r³s³t³ units³
