In a 50 meter long and 10 meter wide rectangular flower bed, lay a layer of 5 cm thick sand. A car can transport 2 cubic meters of sand each time How many times does the sand need to be transported

In a 50 meter long and 10 meter wide rectangular flower bed, lay a layer of 5 cm thick sand. A car can transport 2 cubic meters of sand each time How many times does the sand need to be transported

50 × 10 × 0.05 △ 2 = 12.5 ≈ 13 (Times)

How many cubic meters of sand do you need to lay a layer of 5 cm thick sand on a rectangular ground 50 meters long and 32 meters wide
1. How many cubic meters of sand do you need to lay a layer of 5 cm thick sand on a rectangular ground 50 meters long and 32 meters wide? If a car can transport 1.5 cubic meters of sand at a time, at least how many times?
2. The worker master is going to cut out the largest cube from a cuboid of 10 cm long, 8 cm wide and 4 cm high. What's the volume of this cube?

1. Soil = 50 × 32 × 0.05 = 80 M3
Times = 80 △ 1.5 ≈ 54 times
2. Volume = 4 × 4 × 4 = 64 CC

In a 45 meter long, 28 meter wide rectangular ground, lay a layer of 4 cm thick sand. (1) how many cubic meters of sand do you need? (2) At least how many times does a vehicle transport 1.5 cubic meters of sand each time?

4cm = 0.04m, (1) 45 × 28 × 0.04, = 1260 × 0.04, = 50.4 (M3); answer: need 50.4 m3 of sand. (2) 50.4 △ 1.5 = 33.6 ≈ 34 (Times); answer: 34 times can be transported
