In a 90 meter long, 56 meter wide rectangular ground paved with a layer of 4 cm thick sand (1) How much sand do you need? (2) How many times does it take a car to transport 1, 5M and 179 tons of sand and soil each time?
4cm = 0.04m
Required sand 90x56x0.04 = 201.6m3
At least 201.6 △ 1.5 = 134.4 ≈ 135 times
How much sand does it take to lay a layer of 5cm thick sand on a 50m long and 10m wide rectangular flower bed?
Sorry, there's no reward
5cm = 0.05m 50 × 10 × 0.05 = 25m3 A: 25m3 sand is needed
How many times does a car transport 1.5 cubic meters of sand? I need to calculate the process and answer
Lay a layer of 4cm thick sand on a rectangle 35 meters long and 28 meters wide
(35*28*0.04)/1.5=39.2/1.5=26.13
At least 27 times
