Question

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?

Answer 1

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
