Question

Can anyone plz help????

Answer 1

Answer:

648

Step-by-step explanation:

We see that the figure has 6 sides.  We know that the top side and bottom side are both 9 by 9.  We see that the other 4 sides are all equivalent, as they each have one side that is 9 by 13.5.

$9*9*2=162\\13.5*9*4=486\\486+162=648$

Answer 2

Answer:

Surface area of the cuboid = $648m^2$

Step-by-step explanation:

The given figure is in the shape of a cuboid with the given dimensions:

Length= 13.5 m

Width= 9 m

Height= 9 m

Surface area of the cuboid is:

               =  2((Length*Width)+(Width*Height)+(Height*Length))

Putting the values in the formula:

Area is :

      $=2((13.5*9)+(9*9)+(9*13.5))\\\\=2(121.5+81+121.5)\\\\=2*324\\\\=648m^2$

The Surface area of the cuboid is $648m^2$
