Question

A cube has each of its edges increased in the ratio 3:2.
Find (i) the ratio of the volume of the second cube to that of the
first; (ii) the ratio of the area of a face of the second cube to that
of the first.

Answer 1

Answer:

i) 27:8

ii) 9:4

Step-by-step explanation:

i) Volume of a cube= a³

So, 3: 2

= 3³: 2³

= 27: 8

ii) Area of the face= a²

So, 3: 2

= 3²: 2²

= 9: 4
