Answer 1

Answer:

Given :

20 cubical boxes each with edge 12 meter to be made.

To find :

The cost of tin sheet required at rate of Rs.130 per m²?

Solution :

A cubical edge is 12 meter.

The surface area of the cube is

$SA=6a²$

$SA=6(12)²$

$SA=6\times 144$

$SA=864\ m²$

The cost of tin sheet required at rate of Rs.130 per m² is given by,

$C=864\times 130$

$C=Rs.112320$

• Therefore, the cost of tin sheet required is Rs.112320.
