2.10 g/cm^3
B
0.75 g/cm^3
C
0.32 g/cm^3
D
1.28 g/cm^3
Guida verificata passo dopo passo1
Identify the given quantities: mass (m) = 59.3 g and edge length (l) = 4.30 cm.
Calculate the volume (V) of the wooden cube using the formula for the volume of a cube: \(V = l^3 = (4.30\, \text{cm})^3\).
Use the density formula, which relates mass and volume: \(\text{density} = \frac{m}{V}\).
Substitute the known values of mass and volume into the density formula: \(\text{density} = \frac{59.3\, \text{g}}{(4.30\, \text{cm})^3}\).
Perform the division to find the density in units of g/cm\(^3\).
