A shot with a mass of 30kg and a volume of 1.5 times 10 to the fourth power cubic centimeter, is it hollow or solid by P = m / V? To complete the process and answer (P lead = 2700kg / M third power)

A shot with a mass of 30kg and a volume of 1.5 times 10 to the fourth power cubic centimeter, is it hollow or solid by P = m / V? To complete the process and answer (P lead = 2700kg / M third power)

V lead = m / P = 30kg / 2700kg / m and#179; = o.o1m and#179; < 1.5 × 10 ^ - 2m and#179;
It's hollow

There is a shot put, its mass is 162 grams, but its volume is 64 cubic centimeters, then we can further speculate whether it is solid or hollow?

Lead density = 11.3 g / cm3
Shot put density = 162 △ 64 = 2.53125 g / cm3 ＜ 11.3 g / cm3
So: it's hollow
If you have something you don't understand, please ask again. I wish you progress in your study and make progress! (*^__ ^*)

A shot put weighs 4.5n and has a volume of 0. If the shot is immersed in water, how much buoyancy does it receive? When it is still

F float = ρ liquid GV discharge = 1000kg / M & # 179; × 0.5 × 10 ^ (- 3) M & # 179; × 9.8n/kg = 4.9n
