Answer:
33,680 cm ²
Explanation:
The surface area of a door takes a cuboidal shape, so we will be determining the surface area of a cuboid by using the relation:
[tex]\mathbf{S.A = 2(l*w)+2(1*h)+2(w*h)}[/tex]
Given that;
the height of the door = 200 cm
the length of the door = 3 cm
the width of the door = 80 cm
Then; using the above formula; the Surface area S.A of the door is as follows:
[tex]\mathbf{S.A = 2(3*80)+2(3*200)+2(80*200)} \\ \\ \mathbf{S.A = 2(240)+2(600)+2(16000)} \\ \\[/tex]
[tex]\mathbf{S.A = 480+1200+32000} \\ \\ \mathbf{S.A = 33,680 \ cm^2}[/tex]
