AnnZ [28]

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)

Surface\ area =2(12\times 4+4\times 8+8\times 12)

Surface\ area =2(48+32+96)

Surface\ area =2\times 176

Surface\ area =352 cm^2.

Therefore, the surface area of the figure is 352 cm².
