Li's living room is 6 meters long and 4.8 meters wide. It is planned to lay square bricks on the ground. The square bricks in the shop have the following dimensions: ① side length 10 cm. ② The side length is 35 cm. 6 meters =600 centimeters,

4.8m = 480cm，

The living room area is: 600× 480 = 28.8 = 288,000 square centimeters.

288000÷( 10× 10),

=288000÷ 100,

=2880 (block)

288000÷(50×50),

=288000÷2500,

= 1 15.2 (block),

288000÷(40×40),

=288000÷ 1600,

= 180 (block),

288000÷(35×35),

=288000÷ 1225,

=235. 1 (block),

Because the number of square bricks required for laying a floor with a side length of 10 cm and a side length of 40 cm is an integer,

However, if the floor is paved with square bricks with a side length of 10 cm, then more square bricks will be used and the paving will be messy.

So you should choose a square brick with a side length of 40 cm to lay the living room.

Answer: Pave the living room with square bricks with a side length of 40 cm, on the grounds that it is neat and untidy; Need to buy a square brick like 180.
