Answer:

The length of an edge of the cube = x =
\sqrt[3]{1000} = 10 feet

Explanation:

i.) A cube has a volume of 1000 cubic feet.

ii) A cube has edges which are all the same length, let us say that the length of an edge of the cube = x feet.

iii) therefore the volume of the cube is =
x^(3) = 1000 cubic feet

iv) therefore the length of an edge of the cube = x =
\sqrt[3]{1000} = 10 feet
