Answer:
The amount of water left in the tank is approximately 58.1 cubic meters
Explanation:
step 1
Find the volume of the a cube shape tank
The volume is equal to
![V=b^(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/p181lnr2vy5fb7v8k4b18lbapokbo3749o.png)
we have
![b=4.6\ m](https://img.qammunity.org/2020/formulas/mathematics/college/pom1yd7pcoozqndujlink7g3ov5b9g6fqk.png)
substitute
![V=4.6^(3)=97.336\ m^(3)](https://img.qammunity.org/2020/formulas/mathematics/college/4kbn62een604c003vtg05rijd6rfgluhan.png)
step 2
Find the volume of cone
The volume is equal to
![V=(1)/(3)\pi r^(2)h](https://img.qammunity.org/2020/formulas/mathematics/middle-school/25zf7q1ro45wq3eqm5bebwne6mqikz52qb.png)
we have
![r=2.5\ m](https://img.qammunity.org/2020/formulas/mathematics/college/uh9yjwqglm3y5p467db1b87bpykum2dklh.png)
![h=6\ m](https://img.qammunity.org/2020/formulas/mathematics/high-school/oetui95egqz5uzj12sv4oyibow5qvp9ptd.png)
![\pi =3.14](https://img.qammunity.org/2020/formulas/mathematics/high-school/595myhvi9x0vjp0b1ku7bsoelmk1x8jihg.png)
substitute
![V=(1)/(3)(3.14)(2.5)^(2)(6)](https://img.qammunity.org/2020/formulas/mathematics/college/saet9631mxu40u11nnuru6894x4rxh828o.png)
![V=39.25\ m^(3)](https://img.qammunity.org/2020/formulas/mathematics/college/8cchztyxgt5iv93q77pt4teyduw9hdiini.png)
step 3
Find the difference of the volumes
![97.336\ m^(3)-39.25\ m^(3)=58.1\ m^(3)](https://img.qammunity.org/2020/formulas/mathematics/college/ohnno50xux526p11g1f6r9nlw7mqqbfr0f.png)
