Question

Three solid metal cubes with edges 6 cm. 8 cm and 10 cm respectively a
together and formed into a single cube. Find the volume of new cube
pl solve this ques step by step​

Answer 1

Solution :-

Given : There are three solid metal cubes whose edges are 6 cm, 8 cm and 10 cm respectively.

Formula used :

Volume of cube = (edge)³ cubic units

When we form a new cube by melting the three cube then the sum of the volume of the three cubes is equal to the new cube.

Now,

Volume of new cube = Sum of the volume of the three cubes

= (6³ + 8³ + 10³) cm³

= (216 + 512 + 1000) cm³

= 1728 cm³

Answer : Volume of new cube = 1728 cm³

Answer 2

Answer:

Answer is as follows....

Step-by-step explanation:

Let the new side of cube be equal to A^3.

Volume of three cube together be equal to 6×6×6 +8×8×8+10×10×10= A^3

so 216+512+1000= A^3

so A= 12. (Do cube root of 1728=12 × 12 ×12.) so volume of new cube=1728.
