Question

A cube shaped block has edges that are 3 inches long. A larger block has edges that are twice as long. Compare the surface area of the smaller block to the surface of area of the larger block. Support your answer.

Answer 1

the larger cube has a surface area of 216 and that of smaller cube has 54

Answer 2

Surface area of smaller cube = 3×3×6
=9×6
=54inchsq
Surface area of larger cube=6×6×6
=36×6
=216
Surface area of small cube ÷Surface area of large cube =54÷216
=1÷4
