Hence surface area of figure is option d-174 [tex]m^{2}[/tex]
What is surface area ?
The surface area of an object is the entire area filled by its surfaces. Varying 3D shapes have different surface areas in geometry, which may readily be determined using the formulas we'll learn in this lesson. The surface area is divided into two groups lateral and total.
How to solve ?
the figure contains 3 , 3-d figures
one cube-3 m each,
1 cuboid-legth-9 m,height-3m-breadth-2 m,
1 cuboid- length-5 m, breadth-2m,height-2 m
hence surface area of 3 figures=
cube=[tex]6x^{2}[/tex]=24[tex]m^{2}[/tex]
cuboid=2(lb+bh+hl)=2(10+4+10)=48[tex]m^{2}[/tex]
cuboid=2(lb+bh+hl)=2(18+6+27)=102[tex]m^{2}[/tex]
add all we get =174 [tex]m^{2}[/tex]
