the edge of a cube measures 2.2 * 10^-6 m. what is the volume of the cube in cubic centimeters?

Question

i have trouble in math but i am good well a little good at it and i am going to pre-algebre

Answer 1

The first step we need is the equation to find the volume of a cube. That equation is v = (a)^3.

 

I'm going to give a problem slightly different, but the process is the same.

 

Let's say the edge of the cube is 2 m. We still want to find the volume of the cube in cubic centimeters.

Our edge is measured in meters (m) so we must first convert it to centimeters (cm). There are 100 cm in 1 m. So our cube has an edge of 200 cm.

 

v = (200) ^3

v= 200*200*200

v = 8 000 000 cm^3

After the conversion of m to cm, and substituting the variable (a) with the edge measurement we find that for a cube with an edge that measures 2 m, the volume in cubic centimeters is 8 000 000 cm^3.

 

Let me know how the problem goes with this example to follow.

Answer 2

The edge in cm is 2.2*10^-6 * 100 = 2.2*10^-4 cm   because 100 cm = 1m

 

So the volume is the edge length ^3  = [2.2*10^-4]^3  = 1.1^10 ^-11  cm³   answer
