If 1 dish of craft paint covers an area of 720 square centimeters, how many dishes of paint are required to paint the top surface and the lateral faces of the table shown in the diagram? ignore the bottom of the tabletop and the legs.

The picture in the attached figure

we know that
[top surface area]=36*60-----> 2160 cm²

[ lateral area of the faces of the table ]=15*60*2+15*36*2---> 2880 cm²
[top and lateral area surface]=2160+2880-----> 5040 cm²

If 1 dish of craft paint covers an area of------->  720 cm²
x--------------------------------------------> 5040 cm²
x=5040/720------> x=7 dish

the answer is
7 dishes
