Answer 1

$\mathrm{ \huge \blue{ \underline{ \underline{S \large OLUTION \colon}}}}$



Let the length of the edge of the cube be 'x' cm.


Total surface area = 6x² cm²

Increased length of the edge = 2x

Total surface area = 6(2x)² cm² = 24x² cm².

If the edge of the cube is doubled surface area of the cube increases by 4 times.

Answer 2

Answer:

Step-by-step explanation:

Let the length of the edge of the cube be 'x' cm.

Total surface area = 6x² cm²

Increased length of the edge = 2x

Total surface area = 6(2x)² cm² = 24x² cm².
