Answer:
93.6cm
Step-by-step explanation:
The volume of a cube is equal to one edge length (a) cubed (a^3).
So you start off by taking the cube root of 61.8cm and you get 3.95cm (this is a).
Now you know that's the length of one edge of the cube.
The area of a cube is equal to 6 times one edge length (a) squared (6a^2).
You plug in 3.95cm for a and solve.
6(3.95)^2
6(15.6)
93.6cm
