Let's remember the equation for the volume of a cube: V= x^3 where x is the length of one side Since a cube has equal length for length, width, and height.
Now, use what you're given V= 1331
And put that in terms of x x^3 = 1331
Now solve for x! x= cube root (1331)
Think about it! cube root of 1331 * cube root of 1331 * cube root of 1331... will equal 1331 m^3!
