Both the 10kg stack of books and the 10kg piece of Styrofoam weigh the same amount, 10kg, because weight is a measure of the force due to gravity acting on an object's mass.
It would weigh 10kg.
10kg = 22 (22.0462) lbs.
10kg as it is 8.7kg bigger than 1.3kg
10kg of 250kg expressed as a fraction is 1/25
375g goes into 10kg 26.666667 times.
The answer is 20 lbs.
they carry people. so yes they can carry at least 10kg
40 Packets
That would depend on the volume (density) of the 10kg object.
20lb = 9.072kg
That is approximately 9,080 gm.
