Question

У Петрика є 70 кубиків із яких він хоче побудувати споруду з 8 ярусів. У першому ярусі- 16 кубиків, а в кожному наступному- на 2 кубики менше. Чи вистачить Петрику кубиків , щоб завершити будівництво своєї споруди?

Нi, Петрику  не вистачить кубиків, щоб завершити будівництво своєї споруди

Answer 2

Building Petrik's Structure with Cubes

Petrik has 70 cubes and wants to build a structure with 8 floors. The first floor requires 16 cubes, and each subsequent floor requires 2 cubes less than the previous one. We need to determine if Petrik has enough cubes to complete the construction.

To calculate if Petrik has enough cubes, we can start by finding the total number of cubes needed for the entire structure.

Calculating Total Cubes Needed

The number of cubes needed for each floor can be calculated using the given information: - First floor: 16 cubes - Second floor: 16 - 2 = 14 cubes - Third floor: 14 - 2 = 12 cubes - Fourth floor: 12 - 2 = 10 cubes - Fifth floor: 10 - 2 = 8 cubes - Sixth floor: 8 - 2 = 6 cubes - Seventh floor: 6 - 2 = 4 cubes - Eighth floor: 4 - 2 = 2 cubes

To find the total number of cubes needed, we can sum the cubes required for each floor: 16 + 14 + 12 + 10 + 8 + 6 + 4 + 2 = 72 cubes

Conclusion

Based on the calculations, Petrik needs a total of 72 cubes to complete the structure. Since he only has 70 cubes, he does not have enough cubes to finish the construction.

Therefore, Petrik does not have enough cubes to complete the construction of his structure.
