Answer:
The height of the prism is units ⇒ answer a
The number of blocks needed is 133 ⇒ answer c
Step-by-step explanation:
* Lets explain how to solve the problem
- The volume of a rectangular prism is
→ V = Area of the base × its height
- The volume of the rectangular prism is units³
- The area of its base is units²
- Substitute the values of the volume and area of the base in the rule
∴
- Divide the two sides by
∴ units
* The height of the prism is units
- The volume of each cubic block is units³
- The number of blocks = volume of the prism ÷ volume of the block
∵ The volume of the prism is units³
∵ The volume of each block is units³
∴ The number of blocks = ÷
∴ The number of blocks = 133
* The number of blocks needed is 133
