If a cubical block contains 21,952 cubic inches, how many square feet of paper will be required to cover the entire surface?

Cubical block:

Volume: V=21,952 cubic inches

V=a^3

Edge: a

a^3=21,952 cubic inches

Solving for a:

cubic root (a^3) = cubic root (21,952 cubic inches)

a=28 inches

Surface Area: S=?

S=6a^2

S=6 (28 inches) ^2

S=6 (784 inches^2)

S=4,704 inches^2

S=4,704 inches^2 (1 foot) ^2 / (12 inches) ^2

S=4,704 inches^2 (1 foot^2) / (144 inches^2)

S=32.66666666 feet^2

S=32.67 feet^2

Answer: 32.67 square feet of paper will be required to cover the entire surface.
