If one side of a cube is 15m in length,find its volume

sergeinik [125]

Answer:

$V = 3375~m^{3}$

Step-by-step explanation:

The formula of the volume of a cube is $V = a^{3}$ where "a" would correspond to the length of an edge/side/height/etc.

If we insert our value into the formula, we get the following result:

$V = a^{3}$

$V = 15m^{3}$

$V = 3375~m^{3}~(cubic~meters)$
