=2.5m

Hence, the answer is 2.5m.

Answer 2

Answer:

3:1

Step-by-step explanation:

Volume of cuboid = lbh

= 20×10×15

= 3000m³

Volume of cube = a³

= 10³

= 1000m³

Ratio of both volumes = volume of cuboid / v volume of cube

= 3000/1000

= 3/1

= 3:1

Hence, the ratio of there volumes is 3:1 .
