Answer:
The height of the pyramid is 2cm
Explanation:
From the complete question, we have:
Marble Dimension:
![Length = Width = 6cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/mzt5vntnpqmxur4cel3ckdqjr35fm0etrs.png)
![Height = 8cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/b70pqsqhl84fe8p8f5yztl0l86w44zmbuf.png)
Pyramid
![Length = Width = 6cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/mzt5vntnpqmxur4cel3ckdqjr35fm0etrs.png)
Volume = 1/4th of the volume of the marble
Required
The height of the pyramid
First, calculate the volume of the Marble
![Volume = Length * Width *Height](https://img.qammunity.org/2022/formulas/mathematics/high-school/bx05licvkcq8np9bx0myic9kl2rbi84h9t.png)
So:
![V_1 = 6cm * 6cm * 8cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/h2bpukijwlo6h1ds2gmo9nmfbo87ije4qo.png)
![V_1 = 288cm^3](https://img.qammunity.org/2022/formulas/mathematics/high-school/rs5ovggg1ff6qe8581pf9uwndkg5mi8yu2.png)
Calculate the volume of the Pyramid
![Volume = Length * Width *Height](https://img.qammunity.org/2022/formulas/mathematics/high-school/bx05licvkcq8np9bx0myic9kl2rbi84h9t.png)
![V_2 = 6cm * 6cm * h\ cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/vpa6i94m2a0g59hr4v8gjinxr51ohxqh5j.png)
![V_2 = 36cm^2 h](https://img.qammunity.org/2022/formulas/mathematics/high-school/srktxclf6qbxjvrfeg1d2kp42j14bnu44i.png)
From the question, we understand that:
![V_2 = (V_1)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/meq9abpek9ksvwlcz79oqttw2esbbh0dyb.png)
So, we have:
![36cm^2h = (288cm^3)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/bh82kjw2hx6nxr4u5d2bscm6wq7s162i4r.png)
![36h = (288cm)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/84onzg8vnza82x1fs4upjqb9h4xgdqwc8g.png)
![36h = 72cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/7h4tq8u5exqsv7y2y74wp9lcctpd75tik6.png)
Solve for h
![h = (72cm)/(36)](https://img.qammunity.org/2022/formulas/mathematics/high-school/5nznmco57e3igljbbgu9dhcgvitjp6i4pm.png)
![h =2cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/yz9sdokgjx4k5ytigs1erju19mbp141po3.png)
