Question

A piece of metal is in the shape of a cone of radius 3 cm and height 7 cm is melted to form a cube. Find its side

Answer 1

Answer:

4.04

Step-by-step explanation:

Volume would not change, even if you melt the cone to make a cube

Hence, volume of cone = volume of cube

1/3×pi×r²×h = s³

1/3×22/7×3²×7 = s³

22×3 = s³

S = cube root of 66

S = 4.04124002 ≈4.04
