Compartments 81755

Mr. Milan made a container for sorting waste from wood. The outside will be painted. There will be compartments for plastic and paper on the edges and for glass in the middle. How large areas will he paint with individual colors? The container has a cuboid shape with a base of 1.8x0.5 m and a height of 0.6 m. He won't paint inside. Who would pick it up?

Correct answer:

S =  3.36 m2

Step-by-step explanation:

a=1.8 m b=0.5 m c=0.6 m  S1=(2 a+2 b) c=(2 1.8+2 0.5) 0.6=2569=2.76 m2 S2=2 b c=2 0.5 0.6=53=0.6 m2  S=S1+S2=2.76+0.6=3.36 m2
