Chris knows that's the formula for the surface area of a cube is A=6s to the 2nd power, where s is the cubes side length. He wants to make a wooden puzzle shaped like a cube with sides if length 1/3 foot. What will be the surface area of Chris's puzzle?

Hey user!

your answer is here ...

given that Chris wants to make a wooden puzzle shaped like a cube and the length of each edge of the cube is 1/3 foot.

we know that 1 foot = 30cm

therefore 1/3 foot = 1/3 * 30

= 10 cm

the side (edge) of the cube is 10cm

hence, total surface area of the cube = 6s²

= 6 * 10²

= 6 * 100

= 600cm²

cheers!
