Question

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

Answer 1

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.
