Surface area:
The surface area is given by:
A = 2 * ((s) * (l)) + 2 * ((l) * (w)) + 2 * ((w) * (s))
Where,
s: side
w: with
l: length
Substituting values:
A = 2 * ((12) * (8)) + 2 * ((8) * (2)) + 2 * ((2) * (12))
A = 272 in ^ 2
Lateral area:
The lateral area is given by:
A = 2 * ((s) * (l)) + 2 * ((w) * (s))
Where,
s: side
w: with
l: length
Substituting values:
A = 2 * ((12) * (8)) + 2 * ((2) * (12))
A = 240 in ^ 2
Answer:
lateral area: 240 in ^ 2
surface area: 272 in ^ 2
