Answer 2

Answer:

160 sq. cm.

Step-by-step explanation:

Volume of cube = 64 $cm^3$

therefore, side = 4 cm (Since $\sqrt[3]{64} = 4$ )

When the cuboid is formed one surface of each cube gets hidden so number of surface visible = 5 + 5.

Surface area of one side = 4*4 = 16 sq. cm

No. of faces = 10

Total surface area = 16 * 10 = 160 sq. cm.
