5×0.6×4×4=48

There is a cuboid column in the auditorium. The column is 3.5 meters high and the bottom is a square with a side length of 0.4 meters. Now we need to repaint the column. If we use 125 grams of paint per square meter, how many grams of paint should we use at least?

3.5 × 0.4 × 4 × 125 = 5.6 × 125 = 700 g a: at least 700 g of paint should be used
