There are two bars of the same weight: silver and copper. The dimensions of the silver one are 2x5x6cm.

There are two bars of the same weight: silver and copper. The dimensions of the silver one are 2x5x6cm. Copper bar length 7cm, width 4cm. What is its height?

Let us determine how much a silver bar has if from the condition of our problem we know for sure that its dimensions are 2, 5 and 6 centimeters, respectively:

2 * 5 * 6 = 60.

As we know from the school physics curriculum, body weight can be calculated using the following formula:

m = V * p, where p is the density of the substance that makes up the conditional body.

Find out what the mass of the silver bar is equal to:

60 * 10.5 = 630.

Then the volume of copper:

630: 8.94 ≈ 70.5.

Then the height of the copper bar:

70.5: (7 * 4) ≈ 2.5.

Answer: 2.5 cm.
