Answer 2

Answer:

267 m²

Step-by-step explanation:

Length of the cabinet = 2 m

Breadth of the cabinet = 1.5 m

Height of the cabinet = 3 m

The surface area covered = Total Surface Area of the Cabinet -  Area of the Bottom of the Cabinet

= 2(lb + bh + hl) - lb (l, b and h are length, breadth and height respectively)

= 2(2 × 1.5 + 1.5 × 3 + 3 × 2) - 2 × 1.5

= 2(3 + 4.5 + 6) - 3

= 2 × 13.5 - 3

= 270 - 3

= 267 m²

Hope that helps you...☺
