Answer 1

Answer:

The surface area of the tissue box is 136 in².

Step-by-step explanation:

Given:

Length (l) = 8 inches.

Width   (w) = 4 inches.

Height  (h)=  3 inches.

Now, to find the surface area of tissue box.

So, to get the surface area we put formula:

Surface area = 2(h × w)+2(h × l)+2(w × l)

$Surface\ area = 2(3\times 4)+2(3\times 8)+2(4\times 8).$

$Surface\ area = 2(12)+2(24)+2(32).$

$Surface\ area = 24+48+64.$

$Surface\ area = 136\ in^2.$

Therefore, the surface area of the tissue box is 136 in².
