Answer 2

Answer:

3 more cuboids

Step-by-step explanation:

Given,

The dimension of a cuboid is 25m by 20m by 9m,

Number of cuboids we have = 3,

So, the total volume of each cuboid

V = 25 × 20 × 9

= 5 × 5 × 2 × 2 × 5 × 3 × 3

=  5³ × 6²

Since, volume of a cube = side³

That is, we need a perfect cubic number,

V will be a perfect cubic number if we multiply V by 6

Hence, we need 6 cuboids to make a cube,

Thus, the additional cuboids are needed = 6 - 3 = 3
