Question

Can anyone plz help????

Answer 1

648

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

Surface area of the cuboid =
`648m^2\\`

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\\`
