Question
Jin creates a pattern using the rule “Each layer has 5-blocks”.
The number of cubes in the next shape in Jin’s pattern is
- 18
- 20
- 24
- 25
Hint:
We are given a pattern of blocks of number of cubes made by Jin. The rule used to make pattern is “Each layer has five blocks”. There are three shapes. We have to find the number of cubes used to make the next shape.
The correct answer is: 20
We are given a pattern with number of cubes. The rule used to make the pattern is “Each layer has five blocks”.
One layer is added every time. With each layer, 5 blocks are added.
The number of cubes in the first shape is 5.
The number of cubes in the second shape is (2 × 5) = 10
The number of cubes in the third shape is (3 × 5) = 15
So, the number of cubes in the fourth shape will be (4 × 5 ) = 20
The number of cubes in next shape are 20.
We have to be careful about the order of the shapes.
