Use a net to find the lateral area and the total surface area of the cereal box.

side 12 inches

length 8 in

width 2 inches

what is lateral area:

what is surface area:

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
