Answer:
The surface area of the figure is 352 cm².
Step-by-step explanation:
Given:
Length(l) = 12 cm.
Width(w) = 4 cm.
Height(h) = 8 cm.
Now, to find the surface area.
By putting the formula to get the surface area:
Surface area = 2(l×w+w×h+h×l)
[tex]Surface\ area =2(12\times 4+4\times 8+8\times 12)[/tex]
[tex]Surface\ area =2(48+32+96)[/tex]
[tex]Surface\ area =2\times 176[/tex]
[tex]Surface\ area =352 cm^2.[/tex]
Therefore, the surface area of the figure is 352 cm².
