The cabinet has the shape of a cuboid, the dimensions of which are 80 cm and 55 cm, and a height of 1.8 m. The cabinet is painted twice on the outside. How much paint is used to paint the cabinet if 1kg is enough for 4 m2? (we do not paint the bottom of the cabinet)

Correct answer:

m =  2.65 kg

Step-by-step explanation:

S=0.80 0.55+2 (0.80+0.55) 1.8=5.3 m=2 S/4=2 5.3/4=2.65 kg
