Question

Find the surface area of each figure. Round to the nearest 10th

Answer 1

The surface area of the figure is 352 cm².

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* 4+4* 8+8* 12)`

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

`Surface\ area =2* 176`

`Surface\ area =352 cm^2.`

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