Answer:
1222.45 Kg/m³
Explanation:
The following data were obtained from the question:
Dimension of rectangular block = 22 cm x 13.2 cm x 4.4 cm
Mass (m) = 1562.0 g
Density (D) =?
Next, we shall determine the volume of the rectangular block.
This is illustrated below:
Volume = length x breadth x height
V = 22 cm x 13.2 cm x 4.4 cm
V = 1277.76 cm³
Next, we shall convert 1277.76 cm³ to m³.
This can be obtained as follow:
1 cm³ = 1×10¯⁶ m³
Therefore,
1277.76 cm³ = 1277.76 × 1×10¯⁶
1277.76 cm³ = 1.27776×10¯³ m³
Therefore, 1277.76 cm³ is equivalent to 1.27776×10¯³ m³.
Next, we shall convert 1562.0 g to kg. This can be obtained as follow:
1000 g = 1 kg
Therefore,
1562.0 g = 1562/1000 = 1.562 kg
Therefore, 1562.0 g is equivalent to 1.562 Kg.
Finally, we shall determine the density of rectangular block as follow:
Volume = 1.27776×10¯³ m³.
Mass = 1.562 Kg.
Density =?
Density = mass /volume
Density = 1.562 / 1.27776×10¯³
Density = 1222.45 Kg/m³
Therefore, the density of rectangular block is 1222.45 Kg/m³
