Answer 2

The total surface area of the cuboid is 678 sq. cm.

Step-by-step explanation:

Given : There is a cuboid whose base is square with height 10 cm. If one side face is 120 sq cm.

To find : What is the total surface area of the cuboid ?

Solution :

If one side face is 120 sq cm.

A cuboid whose base is square.

i.e. $A=a^2$

$120=a^2$

$a=\sqrt{120}$

i.e. the length and breadth is $\sqrt{120}$

The height is 10 cm.

The total surface area of the cuboid is

$TSA = 2 (lw + wh + hl)$

$TSA = 2 (\sqrt{120}\times \sqrt{120} + \sqrt{120}\times 10 + 10\times \sqrt{120})$

$TSA = 2 (120+ 10\sqrt{120}+ 10\sqrt{120})$

$TSA = 2 (120+ 20\sqrt{120})$

$TSA =240+ 40\times 10.95$

$TSA =240+ 438$

$TSA =678\ cm^2$

Therefore, the total surface area of the cuboid is 678 sq. cm.
