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)
[tex]Surface\ area = 2(3\times 4)+2(3\times 8)+2(4\times 8).[/tex]
[tex]Surface\ area = 2(12)+2(24)+2(32).[/tex]
[tex]Surface\ area = 24+48+64.[/tex]
[tex]Surface\ area = 136\ in^2.[/tex]
Therefore, the surface area of the tissue box is 136 in².
