Therefore, the cube weighed 7.24 N before you punched a hole in it.
The metal's density is 197.15 cm3 (197.15 106 m3) in the cylindrical hole of the M/V formula. Therefore, = m/V" = W/gV"
Thus, by changing the variable values in the equation, we get the following result: = W/gV" = 0.00342 106 kg/m3 = 3420 kg/m3
Therefore, the metal's density is = 3420 kg/m3.
The cube's weight before drilling a hole. Before you put a hole into the cube, it weighed 7.24 N W = mg where m = mass of cube before drilling hole = V where = density of cube = 3420 kg/m3 and V = initial volume of cube = 216 cm3 = 216 106 m3 and g = acceleration due to gravity = 9.8 m/s2 we have
W=Vg W=3420 kg/m3, 216 106 m3, 9.8 m/s2, and 7.24 n
