Anonymous users2024-01-23Xiao Ming's bathroom should be paved with floor tiles, the bathroom has square meters, and there are two design schemes: a square brick with a side length of 3 decimeters, the unit price is 36 yuan, and a square brick with a side length of 4 decimeters, the unit price is 52 yuan. The square brick with a side length of 3 decimeters needs to cost 48 * 36 = 1668 yuan, and the square brick with a side length of 4 decimeters needs to cost 27 * 52 = 1404 yuan.
27 3 (15 3) = 45 blocks.
For floor tiles, you can choose the polished one, in which case the price should be a little cheaper, but the quality will be a little worse.
When cutting the sewer pipe, you need to leave the thickness of the layup.
Summary. The total area of the bathroom is 4 meters long and 3 meters wide, which is equal to 12 square meters. >>>More
