Question

how many lead cubes of side 2cm could be made from a lead cube of side 10cm. ans is 125​

Answer 1

Answer:

125 lead cubes of side 2cm could be made from a lead cube of side 10cm.

Step-by-step explanation:

We know that , Volume of a cube = ( side)³

side of small cube =2 cm

Volume of small cube=$(2cm)^{3}=8 c.m.^{3}$

side of large lead cube = 10 c.m.

Volume of large cube=$(10 c.m.)^{3} =1000(c.m.)^{3}$

Number of small cube can be made from the large cube is    

                                  =$\frac{volume of large cube}{volume of small cube} \\ \\ \frac{1000}{8} \\ \\=125$
