Rosalie wants to get the entire outside of a cabinet laminated. The cabinet is 3 feet long, 2 feet wide and 5 feet high. The cost of lamination is $2 per square foot. How much will it cost Rosalie to get the cabinet laminated?

The first thing you should do in this case is find the surface area of the cabinet.

We have then that the surface area is:

A = 2 * ((l) * (w)) + 2 * ((l) * (h)) + 2 * ((h) * (w))

Where,

l: long

w: width

h: high

Substituting the values:

A = 2 * ((3) * (2)) + 2 * ((3) * (5)) + 2 * ((5) * (2))

A = 62 feet ^ 2

The cost of lamination is $ 2 per square foot:

So:

(62) * (2) = $ 124

Answer:

it will cost $ 124 Rosalie to get the cabinet laminated
