Question

Can someone please find the area

Answer 1

we know that

surface area is sum of areas of all surfaces

we can see that

there are six surfaces

Out of which there are four rectangles and two trapezoid

so, we can find area of all surfaces

and then we can add them

`S=3* 9+3* 9+3* 6 +3* 12+(1)/(2)* 8* (6+12)+ (1)/(2)* 8* (6+12)`

now, we can simplify it

and we get

`S=3* \:9+3* \:9+3* \:6+3* \:12+8\left(6+12\right)`

`S=27+27+18+36+144`

`S=252m^2`

so, option-B..............Answer
