Answer:
A) 60
B) 225
Step-by-step explanation:
A) The factorization of a number is finding the factors that, when multiplied together, form the original number. As an example, one instance of the factorization of 24 would be 6 and 4, since 6 × 4 = 24.
The prime factorization of a number is finding the factors of a number and restricting them to only include primes, which are numbers with no other factors except themselves and 1.
Hence, all you have to do for A) is to multiply all the factors together, which is , which equates to 60.
B) Since this three-digit number has 5 as a prime factor, it has to end in a 5 or 0. This narrows our search hugely.
Accounting for the fact it has a 3 as a prime factor, the number has 3 × 5 = 15 as a factor. This yet again narrows our search hugely.
Finally, to find the square number, there is actually a really simple way of doing this; simply square 15 to get 225. We can confirm this is a square number because we squared 15 to get that number; hence, 225 is an answer.
Hope this helped!

Answer:
Total volume = 355 cm³
Step-by-step explanation:
Volume of the irregular prism = volume of part A + volume of part B
Volume of part A which is also a rectangular prism = Length × width × height
= (11 - 5) × 5 × 6
= 6 × 5 × 6
= 180 cm³
Volume of rectangular prism B = 5 × 5 × (6 + 5)
= 5 × 5 × 11
= 275 cm³
Total volume = 180 + 175
= 355 cm³
