There are 2 cubes and each cube has 6 sides. There is a 1/6 chance of rolling a 5 for ONE cube (since each side is a different number ranging from 1 to 6). But, since we have to cubes, it would be 1/3. This is because your chance to roll a five is doubled due to 2 cubes.
We can't solve this without knowing the density of the sand. We are given with the side of the cube. From this, we can calculate for the volume. However, to end up with units of mass, you have to use the density. From literature, the density of sand is 1,520 kg/m³. The solution is as follows:
Density = Mass/Volume
1,520 = Mass/s³ = Mass/(1.43)³
Mass = 4,444.79 kg
Answer:
a) 26.3% b) 58.5%
Step-by-step explanation:
(5/19) * 100 = 26.3
(72/123) * 100 = 58.5
