Question

3 Iron small cubes with 3 cm and 4 cm and 5 cm are placed into the big cube req​

Answer 1

Answer :

6 cm

Step-by-Step Explanation :

a = 3cm , b = 4cm , c = 5cm and l = side of req. big cube

Volume of small 3 cubes = Volume of big cube

a^3+b^3+3^3 = l^3

3^3+4^3+5^3 = l^3

27+64+125 = l^3

216 = l^3

cube root of 216 is 6.

So, side of req. cube is 6 cm
