Question

If $5$ cc of paint is required per unit area, estimate the amount of paint (in cc) that will be required to paint this cube on all sides.

• A. $41070$
• B. $8214$
• C. $81070$
• D. $4214$

Answer 1

The correct option is A $41070$

We have to paint the entire surface of the cube so the paint required depends on its total surface area.

Side of the cube $=37$ cm

Therefore, total surface area of the cube $=6\times 37\times 37=6\times 1369=8214$ cm${}^2$

Now, paint required for each unit area $=5$ cc
Therfore, paint required for this cube $=5\times 8214=41070$ cc.

Option (a.) is correct.
