A cube is made from 125 centimetre cubes. What is the surface area of the cube?

125cm^2

Step-by-step explanation:

Cube root of 125 is 5

the big cube has side length of 5 cubes (aka 5 cms)

5 x 5 is 25 (surface area of 1 face)

25*6=125cm^2 (surface area of whole cube)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
