A cone-shaped sand pile has a bottom circumference of 31.4m, a height of 7.2m and a sand weight of 1.5 tons per cubic meter. How many times can it be transported by a 6-ton truck?

A cone-shaped sand pile has a bottom circumference of 31.4m, a height of 7.2m and a sand weight of 1.5 tons per cubic meter. How many times can it be transported by a 6-ton truck?


Bottom radius: 31.4 △ 3.14 △ 2 = 5 (meters), 13 × 3.14 × 52 × 7.2 × 1.5, = 13 × 3.14 × 25 × 7.2 × 1.5, = 78.5 × 3.6, = 282.6 (tons); 282.6 △ 6 ≈ 48 (Times); answer: 48 times can be transported



A conical sand pile, covering an area of 15 square meters, weighs 1.7 tons per cubic meter of sand
How many times will it take to carry this pile of sand?
If 4x = 5Y {X and y are not equal to 0}, then x out of y = {} out of Y {}


1 / 3 × 15 × 2 = 10m3
10 × 1.7 = 17 tons
17 △ 3.4 = 5 times
If 4x = 5Y {X and y are not equal to 0}, then x of y = {4} of y = {5}
