Question

Rubik's cube has a total surface area of 54 ${cm}^2$. Each side of Rubik’s cube contains 9 tiles. The area occupied by a single red tile on Rubik's cube is:

• A. 0.25 cm²
• B. 1 cm²
• C. 2 cm²
• D. None of these

Answer 1

The correct option is B

1 cm²

Given, total surface area of the cube = $6a^2=54c{m}^2$

Area of each face $=a^2=\frac{54}{6}$ = 9 $c{m}^2$

Area of each tile = $\frac{9}{9}$ = 1$c{m}^2$ (As there will be 9 tiles on each side of Rubik’s cube)
