Question

V=4дм3 P=2600 km/m3 m=?​

Answer 1

Ответ:

Объяснение:

V=4 дм3=4*10^-3 м3

P=2600кг/м3

м=V*P=10,4 кг

Answer 2

To find the mass (m) of an object given its volume (V) and density (P), you can use the formula:

$m = V \cdot P$

In this case, you've given the volume V in decimeters cubed (dm^3) and the density P in kilometers per cubic meter (km/m^3). To make sure the units are consistent, we need to convert the volume from dm^3 to m^3.

1 dm^3 = 0.001 m^3

So, you can convert the volume as follows:

$V = 4 \, \text{dm}^3 = 4 \cdot 0.001 \, \text{m}^3 = 0.004 \, \text{m}^3$

Now you can calculate the mass (m):

$m = V \cdot P = 0.004 \, \text{m}^3 \cdot 2600 \, \text{km/m}^3$

To simplify the units, you need to convert kilometers to meters:

1 km = 1000 m

So:

$m = 0.004 \, \text{m}^3 \cdot (2600 \, \text{km/m}^3 \cdot 1000 \, \text{m/km})$

Now calculate the mass:

$m = 0.004 \, \text{m}^3 \cdot 2600 \, \text{km/m}^3 \cdot 1000 \, \text{m/km}$

$m = 10.4 \, \text{kg}$

So, the mass (m) of the object is 10.4 kilograms.
