The height of the cuboid column is 4.5 meters, and the bottom surface is a square with side length of 0.6 meters. Tiles are pasted around the column, and the specification is 0.6x0.6. How many tiles do you need to paste this column We need a simple formula

The height of the cuboid column is 4.5 meters, and the bottom surface is a square with side length of 0.6 meters. Tiles are pasted around the column, and the specification is 0.6x0.6. How many tiles do you need to paste this column We need a simple formula

4.5 * 0.6 * 4 / (0.6 * 0.6) = 30 pieces

There are four cuboid shaped pillars in the hall. The bottom of the pillars is a square with a side length of 20 cm and a height of 4 meters. Tiles should be pasted on the sides of the pillars
What is the area of tile?

Calculate the side area
4m = 400cm
20 × 4 × 400 = 32000 square centimeters. The side area of a column
32000 × 4 = 128000 square centimeters. Side area of four columns
128000 square centimeters = 12.8 square meters. The area to be tiled is 12.8 square meters

A pair of cement columns are cuboids, with a side length of 0.5 meters square at the bottom and a height of 3.2 meters. The volume of a pair of cement columns is: tiles and porcelain are pasted around the columns
Area of rotation

Volume of a pair of such cement columns = [(0.5 × 0.5) × 3.2] × 2 = 1.6 (M3)
Area of ceramic tile = 0.5 × 4 × 3.2 × 2 = 12.8 (M2)
