b) when it is placed on its widest base. the dimensions of the brick are 25 cm x 10cm x 5 cm. (2+2)

Answer 1

Answer:

The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19 and 23, and we have a prime number chart if you need more.

If we can make it by multiplying other whole numbers it is a Composite Number.

Like this:

prime composite

2 is Prime, 3 is Prime, 4 is Composite (=2×2), 5 is Prime, and so on...
