In the school playground, a rectangular pit with a length of 4m, a width of 3M and a depth of 5 decimeters was dug. If the sand weight per square meter is 1.7 tons, how many tons of sand should the school buy to fill the pit .

In the school playground, a rectangular pit with a length of 4m, a width of 3M and a depth of 5 decimeters was dug. If the sand weight per square meter is 1.7 tons, how many tons of sand should the school buy to fill the pit .

Volume of pit: 4 * 3 * 0.5 = 6m3
Sand required: 6 * 1.7 = 10.2 tons

The school transported 7.6 cubic meters of sand. How thick can the sand be laid in a sand pit 5 meters long and 3.8 meters wide

7.6/5/3.8=0.4

The school transported 10 cubic meters of sand. How thick can it be paved in a 10 meter long and 2.5 meter wide sand pit?

10÷（10×2.5）
=10÷25
=0.4m

This is a math problem. How many centimeters thick can you fill 4.5 cubic meters of sand in a 6-meter-long and 5-meter-wide sand pit

4.5 ﹣ 5 ﹣ 6 = 0.15 (m) = 15cm
A: it can be 15 cm thick
